The ads for the American Express charge card point out that with other cards, you run the risk of not being able to pay for dinner because you have gone over your limit. With AmEx, the ad says, you don’t have that worry, because there isn’t any pre-set spending limit.
Does anyone know what they mean by a pre-set limit?
It sounds to me like the limit is not fixed, but is flexible, and you could hit it at any moment without warning. Obviously, AmEx will not allow anyone to put a $500K home on the charge card, so there’s got to be some kind of limit somewhere. Anyone got any ideas?
