My wife and I are only paying 1.59% as merchants. Of course there is also a statement fee, a transaction fee, and who knows what all. What we do is we have a chart. A card transaction of X amount has a specific amount added to it to cover the fee's. Not a single customer has complained.
Great, I would keep that merchant bank unless their other fees are dramatic. Your method is pretty good; it would spur me to pay cash or check. But the legality of it my be questionable if challenged. Some small shops here tried a similar method but that came to a sudden stop pretty quickly, I don't have a definite reason as to why though. Retirement tends to narrow reliable contacts considerably.
