Amex offers are one of my favorite features of American Express cards. These offers can be added to your card in your Amex online account and typically refund a certain amount of money at a certain store if you spend over a certain amount. For example spend $50 at X store, get $10 back. This obviously benefits Amex and these stores, because it serves as advertising for them, shop there once with an Amex offer and you may like it so much you continue to shop there! But still, wise consumers can save a lot of money by maximizing Amex offers.
