No. Add the offer to your Card first, then pay with that Card at checkout. American Express applies the $20 statement credit automatically.
In the Amex app, go to Offers, find Gainful and tap Add to Card. Online, log in to Amex Offers and do the same. You'll get a confirmation email once it's added. Enrollment is limited, so add it before you shop.
Yes. The offer is for a single transaction of $50 or more. Two smaller orders don't add up, and shipping and tax may not count toward the minimum, so aim for a $50 subtotal to be safe.
Yes. A subscription order is a single transaction, so it can qualify. Subscribe & Save pricing is 25% lower, which is why the Subscribe & Save bundles above are built to clear $50 at the subscription price. If you build your own cart, check that your first order total is still $50 or more.
American Express posts the statement credit to the enrolled Card, usually within a few billing cycles after the offer ends. The exact timing is in the offer terms in your Amex account. Gainful can't see or speed up the credit.
The credit is one time, limited to one per Card. If you have more than one eligible Card, each one needs the offer added separately.
Yes. The credit comes from American Express, not from us, so Gainful codes still work. Just make sure the amount charged to your Card after the discount is still $50 or more.
Offer valid 9/21/2026 through 10/23/2026. Enrollment required: you must add the offer to an eligible American Express® Card before purchasing. Enrollment is limited. Spend a minimum of $50 in a single transaction online at gainful.com using your enrolled Card to receive a one-time $20 statement credit. Limit one statement credit per Card. Purchases must be charged directly to your enrolled Card; purchases made with a third-party payment account or with a gift card may not qualify. The full offer terms, including timing of the credit, are shown in your Amex Offer and control over this summary. Statement credits are issued by American Express; Gainful does not issue or control them.
