ENROLLMENT/ELIGIBLE CARDS: Enrollment limited. Must add offer to Card and use the same Card to redeem. Only U.S.-issued American Express® Cards that are enrolled in the Membership Rewards® program at the time of purchase are eligible. Limit 1 enrolled Card per American Express Card online account. Offer is non-transferable. Your enrollment of an eligible American Express Card for this offer extends only to that Card. Your enrollment does not extend to any other Cards that may be linked to your account (such as Additional Cards). ELIGIBLE PURCHASES: Offer valid for purchases at gas station locations in the U.S. An "eligible purchase" means a purchase made with your enrolled Card at U.S. gas station locations by 9/30/17. Offer excludes online purchases and marina fuel or any type of commercial fuel (e.g.- jet fuel) purchases. For purposes of this offer, "gas station" means a merchant that is in the primary business of selling gasoline to consumers. Gas stations may sell other convenience items, but its primary business must be selling gasoline to consumers. The following are NOT considered gas stations: superstores, supermarkets, and warehouse clubs that sell gasoline. For more details please refer to https://www.americanexpress.com/u…-info.html. Purchases may fall outside of the offer period in some cases due to a delay in merchants submitting transactions to us or if the purchase date differs from the date you made the transaction (for example, the purchase date for online orders may be the shipping date). If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the additional points. For example, your transaction will not qualify if it is not made directly with the merchant. In addition, in most cases, you may not receive the additional Membership Rewards points if your transaction is made with an electronic wallet or through a third party. EARNING POINTS: "Get 5X Membership Rewards points" means you will receive 4 additional Membership Rewards point per dollar spent using your enrolled American Express Card in accordance with the terms of this offer. These additional points are in addition to any points you would normally receive for purchases on your Card under the terms of the Membership Rewards program. When we calculate the additional points benefit for Amex EveryDay® Card products, points awarded under this offer will not be included. Additional points will be credited to your Program account within 90 days after 9/30/2017, provided that American Express receives information from the merchant about your qualifying purchase. Terms and conditions for the Membership Rewards program apply. Visit membershiprewards.com/terms or call 1-800-AXP-EARN (297-3276) for more information.
