ThredUP, an online clothing consignment shop, has a great back to school clothing special. When you join, you get $10 off your first purchase. That $10 can also be applied towards shipping (which is $6.95 via UPS Ground) so if you pick something under $3, you can get that completely free. They also have a 20% off promo code (AUGUST20) that you can use to increase the amount you can spend and still get free clothes or you can just use it to get cheaper clothes. I got 2 outfits for my little sister for $5 shipped! Make sure you click BEGIN on the yellow bar (see picture below) to sign up or you may not get the $10 credit.
