I was at Huck's today, and on the counter, they had these little plastic key tags. If you pay inside, with cash, you get 3 cents off gas per gallon. (Fine print: valid at St. Louis-Metro East locations), exp. 6/30/11.

The key tags were FREE. I took two: one for my keys, one for DH's.

Three cents isn't a HUGE savings, but with gas prices going up all the time, we take what we can get.
