If you're an Amazon seller who sources wholesale or private label products, you'll want to check out my video review of JungleScout software (a Chrome Extension). I am an affiliate of JungleScout so I receive compensation if you buy it via my link.
JungleScout is for U.S.-based Amazon sellers (although they are working on a U.K. version too)
I call it 'x-ray' software to find 'pockets of opportunity' within Amazon. See, if you want to compete effectively with wholesale and/or private label products, you need to get an accurate snapshot of the volume and sales of top sellers in your niche. JungleScout helps you do that in minutes (before JungleScout, it took hours).
Good luck and let me know what you think of JungleScout.
