Credit Card Reward Program Description			This Program features both shared and unique benefits for loyalty members and credit card holders. Under the Program, members accumulate points based on purchase activity and earn rewards by reaching certain point thresholds. Members earn rewards in the form of discount savings certificates. Prior to this launch in June 2020, under our previous program, AEO Connected™, we also offered additional rewards for key items such as jeans and bras. Rewards earned are valid through the stated expiration date, which is 60 days from the issuance date of the reward. Rewards not redeemed during the 60-day redemption period are forfeited.
