I understand the change to the Carnival Cruise gift card discount is frustrating @MarkS245273. We do our best to offer a wide range of products at great prices. However, sometimes product pricing can change due to a number of conditions. Our goal is to make sure you have access to high-quality products even if we occasionally need to adjust the discounts we offer. AARP Rewards did briefly have an issue with checkout after the maintenance was completed, that issue has been resolved. Let us know if you're still having trouble checking out.
