Rewards have an expiration date. The expiration date for Rewards earned through order payments, excluding the purchase of Prepaid Credit and Rewards, is dependent on the date on which the Rewards amount is posted to your Rewards & Credit account. If the Rewards were earned by Order payment, please note that the expiration date is 60 days after the Rewards amount is posted into your Rewards & Credit Account. However, it may be longer or shorter depending on special circumstances when Rewards were earned. You can check the expiration date on the My Rewards & Credit page.
