I've been using ThredUp for more than a year. I probably won't sell to them again - initially, it was free and would could get $15-$20 credit fairly easily. However, the new "deposit" thing is very discouraging, and not worth my time to try to stuff a bag with enough to payout. HOWEVER, they have been shipping much more quickly lately, and it's still an easy and fun app to use. I will continue to shop there, and donate my stuff to charity locally.
