Offer is non-transferable. Limit of 1 statement credit per Card Member. You may not receive the statement credit if we receive inaccurate information or are otherwise unable to identify your purchase as qualifying for the offer. For example, you may not receive the statement credit if (a) the merchant uses a third-party to sell their products or services; or (b) the merchant uses a third-party to process or submit your transaction to us (e.g., using mobile or wireless card readers); or (c) you choose to make a purchase using a third-party payment account or make a purchase using a mobile or digital wallet. 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). Statement credit will appear on your billing statement within 90 days after 5/17/2022, provided that American Express receives information from the merchant about your qualifying purchase. Note that American Express may not receive information about your qualifying purchase from merchant until all items/services from your qualifying purchase have been shipped/provided by merchant. Statement credit may be reversed if qualifying purchase is returned/cancelled. If American Express does not receive information that identifies your purchase as qualifying for the offer, you will not receive the statement credit. Limit 1 enrolled Card per American Express Card online account. The enrolled Card account must be active, not past due, canceled, or have a returned payment outstanding to receive the statement credit. Any benefit earned from this offer is in addition to the rewards (i.e. Membership Rewards or cash back) earned as part of your existing Card benefits, but your ability to earn spend-based rewards for the purchase will be based on the amount after any statement credit or other discount is applied. Amex Offers are dynamic and personalized, so the offers you see may change. For questions regarding your Card Account, please call the number on the back of your Card. By adding an offer to a Card, you agree that American Express may send you communications about the offer. POID: K3HP:0001
