>But with 20 million customers a year, and 17% of them paying with cash, the policy will eventually cost Kwik Trip a couple of million dollars a year, McHugh said.

If we figure two-fifths of cash transactions need to be rounded up and the store is losing an average of 1.5 cents each time, their expected losses would be around $2,000, yeah?

If we make the maximally pessimistic assumption that every cash transaction would require rounding down four cents, that's 68,000 customers per year times four cents, which is $136,000 per year.

A more reasonable assumption that half of transactions require rounding down cuts that in half, I suppose.
