I've been "frustrated" with these "low" prices. I use only cash, and even here in WY the # of places allowing you to pump first with cash has dropped. So for the last two weeks in Gillette where I have to go into the Flying J and prepay, I try to give just enough to fill it just shy of clicking off so I don't have to go back in. Darn! Both times I still waaaay overestimated the $$ consumed and had to go back and get my change.
Life is tough here in Wyoming . . .

Was $2.759 I think.

Ps. I've posted this link before and I'll do it again:
