Just wondering. I'm thinking that a lot of branded franchise owners (who don't have that much control over their wholesale prices) hate it. I remember seeing compilations in newspaper websites as well as radio stations getting tips and broadcasting the cheapest prices in each general area. However, this is really easy. Before I need to fill up, I check for the lowest price along my commute home - where I feel I won't get mugged. It's usually a Costco, but even they vary in prices up to 10 cents a gallon.
