Aerpostale is having a Friends & Family event that runs from August 12th – August 15th. You can save 30% off of your purchase both in the stores (take along your coupon) and on-line. When you shop on-line, just use the code FFAUG to have this discount applied to your shopping cart. You can find a location near you here.
If you shop on-line, go through Shop at Home to make your purchase and you will earn 5% of you purchase total back or if you belong to Ebates, you can get 3% cash back. Both sites will also pay you a $5.00 first purchase bonus.
