Gap takes an extra 40% off sitewide via coupon code "HAPPY". Plus, earn $25 in GapCash for every $50 spent. (GapCash is limited to $125; $25 of GapCash can be redeemed for every $50 spent between May 11 and May 15.) Although this is a similar coupon compared to Gap's recent offerings, this discount has no category restrictions. Shipping adds $7, but orders of $50 or more (before coupon) qualify for free shipping. Deal ends March 30.See all Gap Coupons.
