Our local country store never went over $2.13.9, is today at $2.08.9, and I have a charge account there. He's seldom the absolute lowest around, but he's within 7 or 8 cents most of the time. My guess is at least one station in Roanoke is at $2.05.9 or lower, though.
We usually have some of the lowest price gas in the U.S.
I always pay cash, unless I'm totally out of pocket and use a debit card...almost never.
