A lot of fraud has been perpetuated by people shaving fractions of pennies off payrolls etc. Of course it adds up, and nobody's going to be rounding down anything. If a product costs 1.37, you will pay 1.37 with a credit card, and 1.40 with cash. And yeah it's the blue collar slob with two bankruptcies whose going to get his pennies shaved off.
No you won't. I never see charges with fractions of pennies when I use my card at the gas pumps (which charge 9/10¢ extra per gallon, remember); why would I see charges with fractions of nickels when pennies are gone?
