For what reason might a coupon not work?
As long as you click on the “Redeem Coupon” button (and enter a coupon code at checkout if there is one) then you shouldn’t have any problems. Every once in a while a merchant might withdraw their coupon offer without letting us know or they might be having technical difficulties. In such cases please wait an hour or so and try again. If it still does not work then please Contact Us so we can help you to resolve the issue.
