It should certainly be posted and it is against their agreement, but I can't say that I disagree with the practice.

When you use your special cash-back-airline-miles-personalized-insured-super-card the fees to the merchant can top 4+%. When someone is operating on thin margins (10% is not uncommon these days) taking 4% in fees away is taking away 40% of their thin profit.

it's robbery but imagine the loss of business if you DON'T take credit cards.
