Just filled up yesterday for $3.09 a gallon in Massillon, Ohio.
In our area there are some stations with cheaper gas that is of lesser quality, so I avoid my Sam's Club gas because my car mechanic told me to stick to stations around here that have "red, white, and blue" signs. Marathon, Speedway, etc.. He read a review in one of his magazine's he gets for mechanics.
bighill, the only thing I know I can do about it is to watch and try to match when I get gas with when the price is down. It nearly always works to the point I know I'm saving money.
