My knowledge of the topic may have it's flaws, but my understanding is there is a percentage fee involved in all card purchases paid by the merchant (2, 3, or higher percentages, for example). I've always been under the impression that Amex and Discover are denied because they fall under the 3+ because they're adding incentives to the mans, and merchants have a good mind that everyone has Visa or MC to sub, but they're converting because of corporate incentives for Disc and Amex for rewards on usage and companies won't cover the entertainment bill otherwise. It all makes sense, one person pays another to pay another, blah blah blah. As far as personal card usage, never forget that a merchant pays for the convenience, but I'd rather the convenience be part of the package. As a business, I'd rather deal directly with the merchant when possible.
