Points do expire, but the expiration process has a few different factors. Once you earn points, you have ninety (90) days before those earned points will be up for expiration. Those points will expire if they are not redeemed at the end of that month. For example, if you earn points on January 15th, those points will be set to expire at the end of April as the 90th day is in the month of April.
Rewards must be redeemed (picked-up) in-store within thirty (30) days of conversion (or such time as set-forth in a given offer) or the reward will expire.
Offers do expire, but the expiration dates depend on the offer. Click on the offer to see the details and when the offer will expire.
