I know of another business that AmEx messed with by aggressively lowering their credit limit. The company was always current with their payments and their credit was good. It caused a major headache for the company and cash flow had to be restructured because the cc was being used for multiple purposes. AmEx shot themselves in the foot because now the company doesn’t use the AmEx card as much, so they’re missing out on the merchant fees from the inventory and other things the company was using the card for (which is how AmEx makes a lot of it’s money since you can’t carry a balance their $$$ doesn’t come from interest payments.)
I know many businesses that no longer take credit cards because of the high user fees. It’s cutting into their profits.
In this economy (LOL!) not using credit cards = good idea.
Amex does have cards that works just like a credit card with interest, etc. Not all are a “charge card.”
