Aeropostale is also have a friends and family sale in store and online. You can get 30% off everything, including clearance. Just enter code AEROFRIEND12 during checkout. This is good from 8/9-8/12. If you want to shop in store, you can print a coupon on their website.
I found this cute shirt for only $8, so it will only be $5.60 after the coupon code. They have a bunch of graphic tees for $6-$8, hoodies starting at $15, and camis and tanks for $8. Get some back to school shopping done this weekend.
*Remember to shop through Ebates and get 3% cash back.
