Here are 3 reasons to consider selling shoes on Amazon:
1.) There's a lot less competition in shoes than many other categories. (By comparison, shoes is 'wide open' right now). But more importantly:
2.) there are many major store retailers give MASSIVE discounts - up to 90% - when they're clearing out stock onlineand in stores. That's where the fattest margins are for resellers like you and me. We're talking buying major name-brands - Reebok, Nike, Nine West - for (say) $10 and selling them on Amazon for $30 to $40+.)
3.) Return rates are generally lower than you'd expect
To be fair, some major shoe companies may restrict you from selling their brand. So you should try (before you source shoes) to try listing an item to see if you're restricted. For some helpful tips on that, read this tutorial from my trusted partners The Selling Family.
