It isn't the incremental price difference between stations that is killing our budgets--the savings is minimal. Even if I can save ten cents a gallon (unlikely, unless I happen to have a "fuel frenzy" from the grocery store) that amounts to about 2/3 of a gallon of gas on a fill-up, which is about 12-14 miles of driving. If I have to drive more than 7 miles out of my way to get the low price, I lose money. A two-cent savings, which is the typical difference that I see in the posted prices, has a break-even of about a mile (one way.) Yee-ha.
