I don't think so.
American Express charges us higher rates (as a merchant) than either Visa, MC, Discover, or PayPal.
American Express recently started offering higher reqards for their CARDHOLDERS. Turns out that someone had to pay for those extra rewards, and they raised the rates they charged us merchants for accepting the card.
So we stopped taking the card. Apparently lots of other merchants stopped too, because whenever anyone tries to pay with an Amex card and we tell them we don't take it, they usually say something like, "Man, nobody takes Amex anymore. Wonder why that is?"
