what is an american express serve card
However, if youâre going to go the prepaid route, the American Express Serve card is a good low-cost option that can be virtually free if you play your cards right. Serve is offered by American Express, a CreditCardForum advertising partner. In addition to the regular Serve card, there are currently two other offers available: The American Express Serve FREE Reloads and the American Express Serve Cash Back.
