Ready to stock up at Gap? Today (Friday, August 21st) only, shop all you like there and coupon code BDAY will take 40% off and give you free shipping.

Do check out the exclusions—there are many, like women’s swimwear and kids’ sleepwear—but I tested it on a few sale items and it worked. And we all know the best way to use a coupon is on the stuff already on sale, anyway!
