That is probably the only reason why I use credit cards. Make no mistake your paying for those perks, they are just hidden in your everyday purchases. About 15 years ago I got tired of trying to negotiate cash discounts (usually only for larger purchases), and became a loyal discover card user. So, now i'm part of the problem, and the banks are very happy to keep it that way, because they are also making a percent or so on every purchase I make...

The good news is that gas stations offering a few cents off a gallon, small restaurants, etc that have built in cash discounts seem to be more common now than they were just a few years ago.
