The most well-known of these programs is Amex Offers. Nearly all Amex cards are eligible to participate in the program, which is quite simple to use. Simply log in to your Amex account and scroll down to find the card-linked offers. You’ll see dozens of deals and all you have to do is click “add to card” and then spend with that card at the retailer.
Keep in mind that offers can vary from card to card, so if you have multiple Amex cards, you may have more opportunities to save. There’s usually a spend requirement and expiration date tied to the offers.
