thredUP, an online kids clothing swap site, will pay you up to $10 for a box of your gently-used children’s clothing.
To get started, join thredUP for free and pick up your free USPS boxes to fill. Then, thredUP will do the rest and find you a buyer and send you shipping information, at no cost to you.
Not only can you sell your gently used clothes, but you can also buy boxes of clothing at a super low price of $9 plus shipping.
This is a great way to have a continuous system of getting outgrown clothes out the door, make some money and bring in gently used clothing as your children need.
