Zen Arbitrage vs. eFlip: Which is the Better Online Book Arbitrage Software?

eFlip vs. Zen Arbitrage onilne book sourcing software

Online Book Arbitrage Software Battle


In 2015 (5 years ago), I started hearing about “online book arbitrage,” the practice of mining Amazon for cheap merchant fulfilled books that could be resold via FBA (back on Amazon) at a profit.

I’m a big fan of sourcing books for all the well-known reasons (high profit margins, still far more inventory available, etc), so I continued sourcing books offline while keeping my eye on the “online book arbitrage” world. I wondered if Amazon would - infamously -  instill some restrictions, thusly making the practice of online book arbitrage just another “here-today-gone-tomorrow” fad. Alternately, could it be something sustainable?

Four years later, online book arbitrage still works well for many folks. Like other forms of online arbitrage (toys, clothes), it ain’t going nowhere. Sure it’s gotten harder than it was 4 years ago, but that’s where using the right software can help.

The problem is, most software is utter crap. But two providers that kept appearing on my radar were Zen Arbitrage by Peter Valley; and eFlip by Caleb Roth

So I wrote this article to settle “which is best”: Zen Arbitrage or eFlip

I wanted to do the first major review of online book arbitrage that is an in-depth analysis not focused on one small feature or "hype"

First, the one-sentence concept behind online book arbitrage

“Buying merchant fulfilled books on Amazon and reselling back on Amazon at a much higher FBA price.”

That’s it.

If you need a visual, below are two screen captures of a texbook on Amazon. Note how the merchant-fulfilled folks’(those ‘shipping to the customer themselves’) prices - in the first image - are markedly lower than the Amazon FBA (Shipped from Amazon’s warehouse) prices, shown in the 2nd image. Click on each to enlarge them:

Example of merchant fulfilled book price

The above image shows the merchant-fulfilled price for a texbook in 'Good' condition. Below shows the exact same book and condition, but sold by a 3rd party seller using Amazon FBA.

FBA Seller price of texbook example

Now, why would a buyer pay the markedly higher price ($241+) instead of the far lower price ($64)?

Answer: Amazon Prime. Many buyers want their products shipped to them in 1-2 days and don’t want to wait for the (say) 10 days via a merchant-fulfilled’s standard shipping method.

Therein lies the arbitrage opportunity. If you can find the right books on Amazon at a far cheaper price - fulfilled by another 3rd party merchant like yourself, and buy the book, and then sell it via Amazon FBA at a much higher price, you can pocket the difference.

The problem is 1.) hunting and pecking through millions of books on Amazon is incredibly painstaking and infinitely ineffecient; and b.) finding reliable software to help you can be extraordinarily expensive or, as we’ll discover here, highly unethical.


Does online book arbitrage work?

There’s a hint of  “push button money”-type hype around online book arbitrage, which always gives me pause. Not to mention I personally know Amazon sellers who have lost a significant amount of money with it.

Yet there’s enough credible success stories going around (Peter Valley posted screenshots of one of his students doing $87,000 in a month) that it’s clear this system works for those with the right knowledge, persistence, and tools.

But I want to be clear: You’re not going to ‘get rich’ doing any form of online arbitrage. My longtime readers know I never write about unsustainable or over-hyped tools or systems. So before I continue, realize that neither tool we’re covering here creates - or claims to create - “push button” money. And, please,. test before you invest.  If you buy either software tool, buy your flippable book invenotry in small increments at first. (Don't go "whole hog" and spend thousands of dollars on books until you're sure the system works for you and is profitable).


Online Book Arbitrage Software: A Mini-History

While many experts - including me - spoke about doing manual (or semi-automatic) searches using existing tools to conduct online book arbitrage,  Peter alley created the first software (Zen Arbitrage), and wrote the book on it: Online Book Arbitrage.

And at least two competitors - that I know of - soon hit the market modeling themselves (well, outright copying) Zen Arbitrage. In fact, you can read a very intriguing story about  a way-overpriced, unethical competitor here).

The other was a former student of Peter Valley’s and one of the original Zen Arbitrage customers who made a near-duplicate of Zen Arbitrage called “eFlip.”

Rather than get into copycat accusations leveled against eFlip, I’m going to focus solely on what matters to you, the Amazon seller:

  • Which tool is the best at finding flippable books?
  • Which tool offers the best training (this is inarguably as important as the tool’s effectiveness, as I’ll explain later) ?

And most importantly,

  • Which tool can make you the most money?


How do both tools facilitate online book arbitrage?

Zen Arbitrage and eFlip both provide Amazon data in a searchable format, allowing you to identify cheap books you can resell FBA for a profit. Both have free trials, and both are priced at $79/month.

And - I’m actually surprised by this - that’s where both similarities end. Trust me, I looked hard.


Zen Arbitrage Advantages

Zen Arbitrage has quite a few big features, which are totally absent from eFlip. Here are my top 4:

  1. Zen arbitrage immediately shows FBA prices for all books: This is critical because you'll be analyzing hundreds of books at once and you want a 'quick visual' of one of your most important data points - the FBA price (remember our goal is to find books with large jumps in price from merchant-fulfill to FBA.) So, for every result in Zen Arbitrage, you see the lowest price FBA offer. This makes the process for identifying profit as simple as comparing the non-FBA price to the FBA price. That’s all you have to do to find profitable books. Now, eFlip does offer a scaled-down version they call “Outliers,” but it’s on a separate page from their main books database, and is contained within a small subset of their full database. Zen Arbitrage immediately shows FBA offers for 100% of their 20+ million tracked books. 

Zen Arbitrage Software Dashboard

Let me repeat that:

Zen Arbitrage immediately shows FBA offers for 100% of their 20+ million tracked books.

2. Shipping fees included in prices: The prices in Zen Arbitrage instantly show you shipping costs of the book you are purchasing from the 3rd party merchant. With eFlip, you have to click over to Amazon to view shipping costs, which adds an extra step. I know, ‘big deal’ right? It saves you a click, but it also saves you money. When you combine this with Zen Arbitrage showing FBA offers (which eFlip does not for most books), it makes finding profit as simple as comparing the price in the merchant fulfilled column with the price in the FBA column and comparing the two.  In short: I didn’t have to agonize over flipping back and forth between my Zen Arbitrage window and the Amazon page.

3. ISBN Marketplace: This one took me some time to get my head around, but once I had my “a ha” moment it was clear this was a profit monster (and time saver). The Zen Arbitrage “Marketplace” feature is book arbitrage buying and selling platform that does two things:

a.) It lets you sell “leads” of books you find in the Zen Arbitrage database for sale to other members. You’re not selling the actual book, you are letting another member know that “Hey, I researched this ISBN already for you, it’s profitable!”. But the other Zen Arbitrage member has to pay you to tell them what the ISBN is and pay you direct via Paypal. When the member pays, Zen Arbitrage reveals the ISBN to the buyer (and the buyer can proceed to buy it on Amazon.) So it’s a way for you to monetize your searches without actually buying books!

b.) It lets you skip past searching and purchase these “leads” - ISBN access - from other members for a fraction of their expected net profit (the Marketplace calculates all Amazon fees and shows you an estimated net profit before you buy).

This way of making money is a really significant advantage Zen has over eFlip

4. Database size: This is my favorite feature of Zen. Simply put, eFlip doesn’t show many books, and it was clear to me in all my searches that Zen Arbitrage shows a lot more books in the search results. My “gut check” searches show eFlip has as little as 10% of Zen’s results for a random search.

With far more access to profitable books than eFlip, this may be the biggest Zen Arbitrage advantage of all.


eFlip Advantages

I found only one advantage with eFlip.

Multiple product categories: eFlip offers other categories outside of books, such as vinyl and CDs. Books are still the focus, but if you want to diversify outside of books, this is a an option Zen Arbitrage does not offer. My opinion: Vinyl tends to be very niche and something more suitable for eBay (as buyers are looking for close-up images showing condition), and the CD market - when you are buying from a 3rd party merchant to flip on Amazon FBA - is saturated with product and very slim (or no) profit margins. Also, access to Vinyl, CD, and DVD categories means you'll be charged extra accordingly (above eFlip's $79/month charge for access to its main book arbitrage tool). 

eFlip software user interface

Synopsis: Zen Arbitrage offers four significant features that directly translate to more profit potential, with eFlip offering one.

Training & Support

Zen Arbitrage Advantages:

Text Message Support: Zen Arbitrage claims to offer text message support from Peter Valley directly, and when I started my trial, I did get an email with a phone number. I was a little skeptical, but I fired off a text and - albeit 3 hours later - I got a response. I can’t prove it was actually him, but it’s an interesting perk if you have a time sensitive question.

Just to test this again, I recently signed up for a trial of Zen using my programmer’s name, email, and credit card, and sure enough:

Contact Peter Valley

Live webinars: Zen Arbitrage offers live monthly trainings with Peter Valley where he teaches some aspect of the business and answers questions at no additional charge.. Zen Arbitrage has several years of webinar recordings, so it’s almost like getting a huge book flipping training course. For me, this in-person training is worth 10x the subscription price.

Zen Arbitrage Training videos

Training Program: Peter Valley put his 10+ years of book flipping experience into 60+ videos in his training program. They are segmented between “newbie” videos and more advanced training. Videos appeared to be current and regularly updated.  Here's why this training is critical:

Earlier in this article I said the training was equally important as the tool itself. And here’s why: From what I can tell, the top earning folks using Zen Arbitrage are the ones who totally immerse themselves in the Zen-provided training. My gut tells me - based on my own experience providing my own, unrelated software - that a considerable amount of users just want to ‘plug it in and watch it work’. And that’s just not the case. The training is free, use it.

Pick Peter’s Brain: When I signed up, I got an email offering an “ISBN concierge” service, where you can email Peter Valley any book you’re thinking about buying and he’ll do some “back of the napkin” analysis, pointing out why it might be a good buy or a bad buy. (Another Zen user confirmed to me he (Peter) still provides this.)

Documentation Database: Zen Arbitrage has a HUGE searchable knowledge base (over 60 articles) for people who don’t want to sit through videos (like me), and shortcut to quick answers.

Built-In Chat: In the corner of Zen Arbitrage is a chat box to email support and ask questions. There was no one live and online when I checked, but it’s a nice touch that lets you fire off support questions without leaving the tool.


eFlip Advantages

In terms of support, there were no advantages eFlip offered over Zen Arbitrage that I could determine. (To be fair, eFlip did answer my support question several hours after I sent it).

eFlip had about 1/3 the videos by comparison, mostly aimed at a beginner audience, as well as email support.

Synopsis: Zen Arbitrage’s variety of support channels tells me “Peter Valley gives a damn” about his software and his customers.  eFlip felt comparatively like a ghost town.


More Zen Arbitrage Advantages

Keepa charts (HUGE!): I don’t know how he pulled this off, but Zen Arbitrage displays Keepa graphs  in the search results. (You’ll remember a few months ago that Keepa stopped showing sales rank history for free. Not anymore) But in Zen, when you hover over any price or sales rank value, it brings up a box displaying the six-month historical price or sales rank graph from Keepa. Very useful. Screen shot:

Free Keepa Info inside Zen Arbitrage


Sales and profit tracking tool: This won’t replace more robust tools like Inventory Lab, but Zen Arbitrage has a simple, built-in inventory & sales tracking tool. When you buy a book, you can add it to your Sales Tracking page where it crunches numbers and displays profits (and automatically subtracts all Amazon fees). This isn’t a spreadsheet (though you can export it as such ). Rather, it’s a full web-based profit tracking tool ideal for users who want to track profits closely. Screen shot:

Profit tracking books

Beginner’s View: Zen Arbitrage has a cool toggle switch that lets you switch between a “Streamlined” view for beginners, reducing the data on the screen to the bare minimum; and “Enhanced” view - adding four additional columns of data, like trade-in values. I like this because beginning users can get overwhelmed, and it makes the ‘display’ simple for them.

Restricted book check: Textbook restrictions hit the bookselling world hard over the last two years, and Zen Arbitrage’s built-in restriction indicator is not quite as elegant as Check Permission (shameless plug of my own software), but it does let you know if you’re allowed to sell a specific book.

Automated scan of 30 other sites: Zen Arbitrage scans over 30 other bookselling sites - without clicking. Just hover over the Bookfinder.com icon and a popup window appears showing the lowest price copy on the Internet across 30 other bookselling sites. There are still pockets of opportunity in snapping up books not on Amazon. Screen shot:

Bookfinder results in Zen Arbitrage

Live data: I personally don’t think this is a big deal to most sellers, but some heavy duty arbitrage folks want it: live data. When you look up books on Zen Arbitrage, it “grabs” the pricing data live from Amazon. With eFlip, they claim a 2 hour latency


Zen Arbitrage has many key features eFlip lacks, which directly/indirectly translate to more profit potential.

The Verdict?

Zen Arbitrage is the winner here.


Zen Arbitrage has at least 8 significant features that eFlip does not. And although I tried (hard), I couldn’t identify a single feature eFlip had that Zen Arbitrage did not. (You’ll remember years ago that eFlip’s initial release was an almost mirror-copy of Zen).

Thus: While eFlip started as a clone of Zen Arbitrage, it seems it has not progressed, while Zen has been adding tons of features over the years to remain light years ahead of eFlip.

For serious sellers who want to make the most money, Zen Arbitrage is, in my opinion, the far better choice. 

If you’re still squeamish about jumping into any book arbitrage software, Peter Valley has a free ebook that explains exactly how to do online book arbitrage manually, without using any paid tools, here.

    Zen Arbitrage member, and just started using Jordan’s
    CheckPermission extension. Zen arbitrage works great so far,
    including the Marketplace, and I would have to say Check Permissions
    is a Godsend. Don’t know how I did without it for a month. Wait, yes
    I do….I ended up purchasing 8 books that I didn’t realize were restricted.

  • Donna January 16, 2020, 5:19 pm

    I just sat through a couple hours of training on the Anthony Lofrunento listed under Booktrades.biz. They want $3500 to invest in their program & system.
    Did you ever look at this company & do a review?

    • Jordan Malik January 18, 2020, 8:09 pm

      Hi Donna, BookTrades.biz = Book Profits = Textbook Money. They’re one and the same company. There’s a history with them (and, my opinion, it isn’t a good one). You can find out more in this article Peter Valley wrote 2-3 years ago: https://www.fbamastery.com/textbook-money-hacked-zen-arbitrage-got-punked/.

      The lowest-risk way to get into Online Book Arbitrage using software is via Peter Valley’s Zen Arbitrage. His is the first and, in my opinion, the best, and there’s absolutely no reason to purchase any solution that’s more expensive. (The videos you’ll have access to via Zen Arbitrage teach you everything you need to know). You also get a 14-day free trial.

      Rumor (I have to say ‘rumor’ to avoid a lawsuit) is that many BookTrades.biz/Book Profits/Textbook Money customers lose the $3500 they paid and end up migrating over to Zen Arbitrage.

  • Stuart January 14, 2020, 3:40 pm

    Hi Jordan,
    I have nearly signed up for Zen Arbitrage a few times, but I am a cautious type and never actually took the plunge. I did find Peter Valley to be very helpful and very good at responding to questions.
    One thing that concerned me in the Jim Pickins review, was when he said that the Zen database was a bit out of date in that you might find a book you wanted to buy but when you went to buy it, it was already sold. The reviewer said this happened a lot more with Zen than with eFlip.
    Did you find that to be a problem? I’m not sure from your review whether you actually bought many books or if you just mostly looked at the database results.
    Great website by the way!

    • Jordan Malik January 15, 2020, 12:39 pm

      Hi Stuart:

      Note that the Jim Pickins review is over 3 years old.

      I do remember Peter said in a recent webinar that the prices on Zen are 100% live. I wasn’t totally sure so I reached out to him, this is what he said:

      “About a year ago we switched over to 100% live pricing. So we get data directly from Amazon in real-time, meaning the prices are always current down to the second (we’re the only tool doing this now).”

      • Stuart Roberts January 17, 2020, 4:17 am

        Thanks Jordan, I was hoping that was the case, but it’s good to know for sure.

  • david January 2, 2020, 2:37 am

    What a good blog!
    A few months ago Petter Valey created a new software called Zen Zenith.
    could you talk about that?

    • Jordan Malik January 2, 2020, 8:09 am

      Hi David, Zen Zenith is closed to the public now, from what I know. I didn’t have time to test it out (it was sold out in a couple hours). I don’t know if he’s reopening it anytime soon.

  • Leroux Redman December 28, 2019, 10:02 am

    Jordan, great article. What have you heard, seen or researched on BookTrades.biz, I watched their ‘live’ webinar (promotion) last week. This webinar is what has me researching textbook arbitrage and looking into other trustworthy systems. I appreciate your recommendations.

  • Cathy December 17, 2019, 9:03 am

    Great comparison review! We were wanting to sign up with Entrepreneur Today but special one time offer was $3500 marked down from $7000. Thank goodness doing more research. Excited to learn from your suggested education links!

    Thanks so much!

  • Darryl November 16, 2019, 8:39 pm

    Hi Jordan!
    Thank you very much for this information.
    This is my very first look at online selling through Amazon.
    My wife and I are planning to retire in the second quarter of 2020, and I’ve been thinking about a means of income for our retirement that will not entail going to a job; trading my time for money. I’ve done that for too many years.
    Thanks again, and many blessings to you in your endeavors.

    Sincerely, DMAC

    • Jordan Malik November 17, 2019, 3:00 pm

      You’re welcome Darryl. P.S. If you need beginner step-by-step help on how to sell on Amazon (not “book-specific”), here is some free beginner help.

  • Russell Edwards October 7, 2019, 6:58 am

    Jordan, thanks for the unbiased opinion. But if I could get one more comparison from you. I have been hit with a lot of FB ads for Entrepreneur Now. They sound very impressive but joining cost and monthly fees seem pretty high. Have you done a comparison between Zen and Entrepreneur Now? Thanks in advance for your knowledge and honesty.

    • Jordan Malik October 7, 2019, 10:23 am

      “Entrepreneur Now” is a makeshift facebook page, has nothing to do with “EntrepreneurNow.com”. If the “Entrepreneur Now” thing is indeed $3,000, I don’t know how anyone would entertain that when 1.) ZenArbitrage is a mere fraction of the price, and 2.) The creators/founders of “Entrepreneur Now” have (my opinion) zero practical knowledge of the used book business. (In other words, they’re hawking something they’ve probably never done themselves). Whereas Peter Valley (ZenArbitrage founder) not only sourced books starting 10+ years ago when his skateboard was his only mode of transportation, but he has built – in my opinion – the very first and defacto standard of online book arbitrage software.

      • Tony October 9, 2019, 5:24 pm

        Russell is correct. I’ve been getting hit with FB ads from Entrepreneur Now as well. They are pushing software and training for $3k as the discount pricing from $5.5k asking. I found this article after listening to their pitch. Had a hunch there was more information about the topic out there somewhere. Thanks so much for your review. It is greatly appreciated. I can now make a better-educated decision on how to move forward; which will obviously save me thousand right out the gate.

      • Jordan Malik October 9, 2019, 9:52 pm

        Update. I did some homework and discovered the “Enterpreneur Now” thing is the same entity as “Textbook Money” by Luke Lambo (his natural birthright name, obviously) . BONUS: The (near?) crime Textbook Money made against Peter Valley’s Zen Arbitrage is documented here: https://www.fbamastery.com/textbook-money-hacked-zen-arbitrage-got-punked/

  • Bill Maddox September 30, 2019, 11:33 pm

    I’m living in the Philippines. Does this software and book buying and selling program with Amazon make sense internationally? Is there an avenue to buy/ sell without all the shipping? For example a third party storage area that ships for you, to cut down on the international shipping charges. Thank You

    • Peter Valley, founder, ZenArbitrage.com October 1, 2019, 11:23 am

      Hi Bill. Peter Valley here.

      We have TONS of international members. Here is how it works: You find profitable books on Amazon US, have them shipped to our US prep service, who then ships them into Amazon US warehouses.

      We get you set up with all of that.

      And the prep service is a flat $1 per item. Very simple.

      The prep service basically makes your location irrelevant, so its an awesome resources.

      Hope that helps.


      • Jordan Malik October 1, 2019, 1:53 pm

        Hey Peter (aka Flash), thank you for answering this customer before I could!

With no success, I need to make a extra 2-4 k a month from something I can do part time as I am a full time registed nurse , what’s the best real
    Way you know of to make money online , thanks for your time

  • kris September 8, 2019, 8:04 am

    Hi, thank you very much about the article and the time spent in research. I wonder if you have heart of Book Profits. They claim better software and are much more expensive. My q to you is if you know much more detailed in depth and if you care to share. Thanks

    • Jordan Malik September 8, 2019, 3:27 pm

      Sorry Kris, I have never heard of BookProfits, nor could I find reputable/trustworthy information about them.

      • Christopher Stansberry October 12, 2019, 11:11 am

        Hello there. Not sure how old this thread is but I’ve been looking into these opportunities myself and I can answer the Book Profits inquiry: that is also “Lambo Luke”

    • Lee November 5, 2019, 2:09 pm

      I am also just looking into these opportunities and have discover Book Profits is the same people as Textbook Money.
      Same people charging more money for the same info!

      • Jordan Malik November 5, 2019, 10:08 pm

        Good eye, Lee. Yes they (Book Profits and Textbook Money) appear to be one and the same, and I personally don’t recommend either one.

  • Terry Gray August 26, 2019, 6:21 pm

  • Craig July 24, 2019, 8:17 am

    Hi Jordan,

    Thanks for your feedback and review on Zen AR vs E-Flip. I am a user of Zen Arbitrge and LOVE it. It has proven to make me money. I do want to say that even though Zen does check restrictions, I use your your Check Permission extension [Ed. note: CheckPermission instantly shows whether or not you are approved to sell any item on Amazon] and love it.

    I could not do without Check Permission in my business. It not only checks the book category, it checks all categories, which is a BIG time saver and valuable tool for me.

    Just wanted to let you know your Check Permission platform is a great tool.


    • Jordan Malik July 24, 2019, 8:25 am

      Craig – great to hear both Zen Arbitrage and CheckPermission are working for you. Super happy to see you crushing it too! Keep up the excellent work.

      • Terry Gray August 27, 2019, 4:11 pm

        Jordan, so Check Permission is particular to each seller’s individual account, right? And not just an overall restriction notice that may affect some sellers but not others? Of course, I’m talking about books. Also, what about sub-conditions? Most of the time when I find a book I’m restricted on, I’m only restricted in selling N and LN copies. Probably 99% of the time I can sell VG, G, & A copies. Does CP dive down into these particulars? Finally is there a CP phone app for when sourcing in the field, or is it only for the computer? Thanks.

        • Jordan Malik August 27, 2019, 4:43 pm

          Hi Terry, correct – CheckPermission is particular to each seller’s individual account. Yes, sub-conditions are mentioned. There is no CP phone app. I’m not sure what other folks use, but when I’m mobile scouting I use the Amazon seller app to tell me whether or not I’m restricted from any particular item.

  • Charles July 5, 2019, 3:41 pm

    Hello Jordan,
    First, please allow me to thank you for your review. I found it to be both honest and insightful.
    I’ve been searching for a way to subsidize my social security income but to no avail.
    I’m trying to sell on eBay but have a hard time sourcing and listing enough stuff to make any money.
    I need to tell you that I’m at the end of my rope and can’t afford to keep buying stuff
    that just doesn’t work !!!
    My computer skills are not that good but I need something that I can do from home.
    Jordan, will Zen Arbitrage work for me ?
    What I’m really asking is can a “Baby Boomer” with no real computer skills learn this stuff and net at least $2,000 a month ?
    Besides the $79 per month what else will I need to get started ?
    They never seem to tell you about all the – ADD ON’s – needed, until after you’ve bought the course.
    Because I live on a small fixed income it’s imperative that I know up front exactly what my monthly expenses will be.
    Jordan, you’ve proven yourself to be an honorable man (A Rarity Online) and I await your reply..
    Thanks for your time and effort.
    Charles …

    • Jordan Malik July 6, 2019, 2:52 pm

      Hi Charles!

      I don’t recommend Zen Arbitrage for anyone who is brand new to the world of online selling. Thus, here is what I recommend, based on what you’ve told me:

      1.) Re: computer skils, I recommend you take a local inexpensive adult-learning/evening course that teaches the basics of online selling (eBay, Amazon, or both). If no such course exists, I recommend you find one that teaches Internet basics.
      2.) Afterward, if you have never sold on Amazon before, I recommend you take this (free), easy step-by-step course by my trusted partners The Selling Family. This is so you can learn the basics of selling on Amazon (this is not about selling books, it’s about selling products overall).
      3.) Then, I recommend you take an easy-to-understand course about finding and selling used books to resell on Amazon. This is a good option, also from The Selling Family. This is so you get to understand the basics of selling used books online.
      4.) Only after you’ve done the first 3 steps outlined above, then you should consider using Zen Arbitrage.

      I know the above is a lengthy “assignment”, but I encourage that approach versus just diving into any reselling software.

      Good luck and keep me posted!

  • Jacleen Allen June 29, 2019, 9:46 pm

    Hi Jordan, this article is FASCINATING, although not surpising. Having been kicked out of the Book Trades/Book Arbitrage authoritarian “community” because I voiced some concerns about the high monthly fee for the software I now understand clearly why people who voice these kinds of concerns are swiftly dealt with. I KNEW the moniker “Lambo Luke” was a red flag but I had never heard of book arbitrage before and it sounded perfect for me.. and it HAS been.. except for Amazon’s bloody gating.. grrr!

    Anyway, just wanted to thank you for this article. I don’t feel so isolated and rejected anymore lol

    • Jordan Malik June 29, 2019, 9:50 pm

      Jacleen thanks for the note. I have heard from other Amazon book sellers that the exorbitantly priced software (provided by the guy named after a Ferrari) is nothing more than marketing hype. I encourage you to check out Zen Arbitrage. And as far as gating is concerned, my CheckPermission software will tell you (immediately, while you are looking at a book on Amazon), whether or not you are permitted to sell any item (including books).

    Hi Jordan

    What a fantastic review! Thanks a lot. It’s much appreciated and would help serious readers who are considering both options, make informed decisions.

    Among Keepa and Helium 10, may I know which is a better tool to analyze sales rank history ? I’ve heard that Helium 10 offers the service for free like Keepa used to until February 2019? I just wanted some confirmation on that. Thank you.

    • Jordan Malik May 15, 2019, 11:16 am

      Hi Perviz:

      To my knowlege, both Helium 10 and Keepa are reputable providers of sales rank.

        Thank you, Jordan. Appreciate that.

    Hi Jordan, I was wondering if you had any input on how Tactical Arbitrage’s Library Search fits into the mix?

    • Jordan Malik May 9, 2019, 9:50 am

      Hi Beth. I’ve heard (but have not yet verified) that Tactica Arbitrage’s book arbitrage features are limited when compared to Zen (and even eFlip). However, I have heard excellent things about Tactical Arbitrage with regards to its usefullness in arbitrage overall (Amazon sellers using it to source regular online retail goods in categories like clothing, toys, baby, kitchen/bath, etc).

  • Kyle May 9, 2019, 5:18 am

    Thank you Jordan! I have used eFLIP in the past but have not been fond of it lately. Encouraging to know I can give Zen a whirl!
    Do you use it to buy books to sell yearround or just at textbook seasons? What has been your experience?

    • Jordan Malik May 9, 2019, 9:54 am

      Hi Kyle, online book arbitrage is not a major part of my income (other aspects of my business like my software, private label products, my newsletter, and other product sourcing methods take up the majority of my time.) That said, I have randomly tested Zen over the months and I do find markedly profitable books with it. And yes I am a big fan of sourcing books well ahead of the traditional “back to school” seasons and waiting for the prices to spike before I send them into Amazon’s warehouses. BUT other experts agree that the opportunity for textbooks is year-round, not just the back to school seasons.

    Hi Jordan,
    Last night Lambo Luke had a webinar on his new book arbitrage software which I’m sure you are aware of. It is $997 plus $197 a month. The testimonials were really unbelievable but I am
    familiar with this company and had my doubts.

  • Mikr May 8, 2019, 3:59 pm

    Hi Jordan. You’re timing is great. I’ve been reading and viewing videos on this very subject. I’ve been following you for a few months now and I have come to value you opinion. But this time it’s kinda hard to tell who is really the clear winner after a video/article I just reviewed today [Jim Pickens’ promotional article of eFlip], which review concludes that eFlip is the winner. Both your post and his have different reasons and arguments, and are both from unpaid sources. So my question is, how does someone who wants to get into book arbitrage and is a complete newbie pick a software when they don’t know what they don’t know? BTW, I hope I didn’t offend you in any way, because that’s not my intent. I’m just trying to figure out which one is REALLY the best.

    • Jordan Malik May 8, 2019, 5:45 pm

      Hi Mikr.

      Kindly note that Jim Pickins’ article is about 14 months old now (LOTS has changed for both eFlip and Zen in terms of features), but more importantly, Jim’s article has affiliate links/buttons that click through to eFlip throughout it, where he is eligible for a commission if someone ends up buying eFlip through his link. (The landing page after you click through says “Jim Pickens Special.”) But I want to be clear: that isn’t a ‘dig’ against Jim nor his crediblity. I also have affiliate links to other products/services on other pages of my blog/newsletters etc., but in cases like this (where I’m comparing two or more services), I’ll either have affiliate links to all of the solutions and disclose that to the reader, OR, as in the above case (Zen vs. eFlip), NO affiliate links. The goal? The reader gets a fair, unbiased view.

      That leads me to you, my good reader. My opinion certainly isn’t the final word! My suggestion is read all the reviews and fully test out each solution (or any tool that is reasonably priced and/or with a trial period) and choose what you feel is right for you.

      • Mikr May 10, 2019, 8:33 am

        Thank you Jordan. I didn’t realize that Pickens’ review was that old. Your opinion is valued.

    • Peter Valley May 10, 2019, 9:12 am

      Peter Valley, Zen Arbitrage founder here. Just got pinged about this article (I’m always the last to know) and wanted to weigh in on this comment in particular.

      1. That review you cited [Jim Pickens’ review of eFlip] is over 3 years old.
      2. It is 100% a paid review (affiliate links are all over it).
      3. Jim’s critiques are suscpicously yet verifiably false (you’re welcome to verify by starting a 14 day free trial of Zen Arbitrage at http://www.zenarbitrage.co, to compare the difference in peformance yourself)

      A couple more points:

      1. Jordan’s review is honest & uncompensated (remember: he wrote it and posted it without me knowing until days later).
      2. Jordan’s review seems to rely on objective, 100% verifiable facts (again, easily proven with a free trial to both tools, to compare side by side).
      3. I’ve offered a full refund at any point to anyone who compares both and chooses eflipper, and out of hundreds of people not one person has ever found eflip to be better (email me for a huge PDF of unsolicited, critical comments from ex-eflip users).

      One tiny deficiency in a tool can cost you hundreds of dollars a month (or more). Compound those across many deficiencies over many months, and relying on a paid review for your decision just cost you tens or hundreds of thousands of dollars. In this review, Jordan highlighted about 10 things that directly translate into more profit for Zen Arbitrage users (my words, not Jordan’s).

      Which tool you choose for your business is no small decision, and it is unwise to rely on paid reviews without verifying.

      Long comment, but want to end by highlighting what a testimony it is to Jordan’s character that he didn’t ask me for an affiliate link for this review (or even tell me he was writing it). He forfeited an untold amount of affiliate revenue to bring you guys an honest review. How many other bloggers or YouTube “gurus” would turn down money to serve their readers? Amazing.

        I’m a baby boomer newbie, and I’m doing my research & due diligence concerning Amazon, and to be a reseller. This review was/is very beneficial to compare, and I appreciate all the valuable insights from the comments too. So much to learn, and so difficult to find reputable & trustworthy sources to get information. That being said, I purchased the courses from “The Selling Family”, so I’m learning the basics there. Then I ordered the ‘hard copy’ book from Peter Valley on Online Book Arbitrage, so I’m super excited to eventually getting started. Peter & Jordan thank you for you honesty, integrity, and unbiased recommendations! (Jordan, at some point I’m confident I’ll order your CheckPermission software too, because it seems like it will dovetail nicely with Zen Arbitrage) Thanks again & God Bless!

        • Jordan Malik January 12, 2020, 11:25 am

          Awesome Rick, way to go (you’re *taking Action*!) Thanks for the kind words too. Now go crush it!

  • Alex May 7, 2019, 9:58 pm

    Was wondering if you still feel the same way about Zen over eFlip?

    • Jordan Malik May 7, 2019, 10:03 pm

      Hi, Alex – yes that article is brand new and was published on May 7, 2019
