I just use this site to sell my old textbooks, and even if they're international or older editions, I get at least a few bucks. Love it! And my check came in the mail within a few days!
Love that they always have sales and their regular priced items aren't that expensive. Although, sometimes they don't always have the size you want, but then again, who doesn't love Forever 21?
I like the variety of categories of clothing items they have, but the style of clothes is a bit limited. Good for the price though! They always have items for sale, so those are always a steal!
You have a 50/50 chance of buying either something crappy or something of decent quality. A lot of the buyers ship the items from China, so it takes anywhere from a week to a month for the item to arrive. And some of the buyers/sellers are unreasonable sometimes, so it's really a matter of luck.
On the bright side, sometimes they have good quality items for a decent price!
