Amex is doing a scam on the public by advertising in the media and on its online site that there is no pre-set limit on their charge card which you pay in full each month. Maybe in the past that was true but when you are embarrased after a DECLINE at the merchant you find that they are perpetrating false advertising on the public and they don't have the decency of any warning of the limit till it is too late. Shame on you AMEX
the credit card companies and banks want the help of the taxpayers but they act like loanshark mobsters with their customers who have excellent payment records
