Don't waste your time if you think you're going to make any money.
I honestly feel like I should've just thrown my stuff away instead of Thred Up insulting me with a ridiculous payout of $0 for a brand new (never used) Coach wristlet (which they had listed as gently used)! Then charging $10 to return clothing they don't like, so I end up making ZERO dollars. I could've thrown it in the garbage and felt better about it - rather than feeling like I got scammed!
