OFFER TERMS

ENROLLMENT/ELIGIBLE CARDS: Enrollment is limited. Must first add offer to Card and then 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. 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 only at Amazon.com and via the US Amazon mobile app using your enrolled American Express Card after enrollment through 1/31/18. Not valid at international sites owned and/or operated by Amazon or websites affiliated with/linked to/from Amazon.com. Offer only applies to the purchase of a non-discounted annual Amazon Prime membership, and does not apply to other Amazon memberships or subscriptions including but not limited to monthly Amazon Prime membership, Amazon Fresh, Prime Video or Prime Student. To the extent Membership Rewards points are used toward purchases, such purchases do not qualify for this offer. 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. If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the additional points. EARNING POINTS: Limit 1 enrolled Card per American Express Card online account and limit of 5,000 additional Membership Rewards points per Card. 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 Membership Rewards program account within 90 days after 3/2/18, 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. Participating partners and available rewards are subject to change without notice. The value of Membership Rewards points varies according to how you choose to use them.
