i've yet to meet a customer that only has amex
Many businesses only have corp AMEX cards. We had a lot of problems with processing AMEX cards (according to them, if a customer doesn't want to pay the charge for ANY reason, tough luck to the merchant), so we stopped accepting it for most customers. However, we kept the account active for many months just because of one big customer that only had AMEX.
