Do not sell clothes on this site - they take 7-8 weeks to process your bag, and will pay you pennies (and during the time you are waiting, they may change what brands they accept, and too bad for you). Since their payouts are so pitifully low, you may end up owing THEM for a bag of clothes if you opt to get them back. Shameful! There are numerous stories of people finding their rejected clothing items for sale on the site as well, which is highly suspicious. I would recommend you try LikeTwice.com, or else consign locally. Even donating and getting the tax deduction would be better financially.
For buying, the site used to be a good deal, but they've raised their prices dramatically. Why would I pay more to buy a used Old Navy or GAP item that I can't try on and have to pay return shipping on if it doesn't fit, when I can pay the same (or less) for the new item in the store? No thanks.
