ThredUP is the largest online consignment and thrift store that pays for used clothing and accepts donated items, as well. If you want to sell, ThredUP sends you a Clean Out Bag to fill with whatever you don’t want and schedule for pickup. That doesn't mean you can just send anything, though. ThredUP's standard is to ask yourself if you would give the item to your best friend. Items cannot show signs of wear, damage, or alterations. On the other hand, if you donate, ThredUP will give $5 per bag to a charity of your choice and send you a tax receipt. So if you’re going to toss your clothes out anyway, you may as well try ThredUP.
The Fine Print: The catch? You don’t know how much you’ll be paid until ThredUP assesses the bag. On average, ThredUP accepts 40% of the items in the bag. If you want your unaccepted items back, ThredUP charges a $10.99 shipping fee. Otherwise, they’re resold or recycled.
