GAP Mystery Cash coupon + 40% off, no exclusions - check email (YMMV)
Check your email today for a message from Gap titled "Love cash? Love no exclusions? You get both today…". It includes a "mystery cash" code good through 7/30/16. The ones I've seen so far have been for $5 off, but you can stack up to 5 codes on one purchase. 40% off code is HAPPY and is good through 7/23/16 (until they come up with their next 40% off coupon :p).
