I haven't used the offer yet. Is it still showing for you? If it's gone, it was probably one trip/transaction.
here are the terms:
Offer Terms
ENROLLMENT/ELIGIBLE CARDS: Enrollment limited. Must first add offer to Card and then use 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 Card Member across all American Express offer channels. 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 the same Membership Rewards program account (such as Additional Cards). Offer is non-transferable. ELIGIBLE PURCHASES: Offer valid at US locations, online at US website or via US mobile app. Valid at any participating location in the US. Not valid on purchases shipped outside of the US. Excludes customer service phone orders. Excludes in-Club optical centers and eye doctors. Excludes prescription and photo transactions made via mobile app. Excludes Sam's Club fuel, first time memberships purchased online and third party services offered to Sam's Club Members (Auto Buying Program, Payroll, Stationary, Checks, Healthcare, Legal Zoom, Photo Center, Business Payment Solutions,
Samsclubcontacts.com, Accounting Services, Business Lending Center, Identity Protection Service, Business Printing, Instacart Groceries, home improvement services, travel and entertainment, pest control, smart home security, and mortgage). 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: You will receive 4 additional Membership Rewards points per eligible dollar spent using your enrolled American Express Card in accordance with the terms of this offer. The enrolled Card account must be active, not be past due, canceled or have a returned payment outstanding to receive the additional Membership Rewards points. Any additional points you receive through this offer are in addition to the points you would normally receive for purchases charged to your Card, but the number of additional points you receive will be based on the purchase price after any credit or other discount is applied. 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 12/31/2019, provided that American Express receives information from the merchant about your qualifying purchase. We may not credit additional points to, or we may take away additional points that have been credited to, your program account if the qualifying purchase is returned/cancelled. Terms and conditions for the Membership Rewards program apply. Visit
membershiprewards.com/terms 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. To learn more, go to
