Haha ok thanks for clearing it up!I've bought pretty much everything and the numbers are always similar no matter what he merchandise is.
You will find that 20-30% of your Nikes will be good looking shoes that sell well. The rest will be in odd sizes and colours and dont sell as well. The ones you will be left with be butt ugly or in sizes only a bear could wear.
If it's a good deal there's no risk but it can be a lot of work for small profit.
