How do I redeem my GapCash?
You can redeem $25 in GapCash for every $50 you spend at Gap stores and online during the specified redemption period. If you earned a $50 or $75 GapCash reward, you do not have to spend $100 or $150 to redeem. You have the flexibility to spend as little as $50 and still save $25; however, you will forfeit your remaining GapCash value. There is no limit to how many GapCash rewards you can redeem but you can only redeem one per transaction
