One of the easiest options for buying a prepaid American Express gift card is purchasing the card directly from the American Express website. Once purchased, you can either use the card yourself or have it shipped directly to somebody else as a gift.
American Express gift cards can also be purchased at a number of major retail stores. Examples of stores where American Express gift cards can be purchased include Walmart, Walgreens, Kroger, Albertsons and CVS. There is generally a small fee associated with the purchase. The gift cards can be loaded for any amount at the time of purchase.
