My friends and I are always going there to shop and sell clothes. If you want to sell clothes, make sure that you have your drivers liscense(you have to be 18). Also, dont expect to get a lot of money. BX usually resells nice designer jeans for about $40 so you would get $20 in trade or about 17-18 dollars in cash. But if you do have some out of the ordinary, weird stuff that you wont ever wear definitely try and sell it. If youre into vintage shopping, Buffalo Exchange is great for finding out of the ordinary clothes! There are some really cool pieces that arent that expensive.
