While the amounts he mentioned were extreme, gas stations needing an extra turn or that are a little further up the road generally have to price their gas lower. Its quite possible these gas stations will have a few cents of extra pricing power for the convenience. I'd prefer the dumb maps that do not give my supplier a price advantage even if its a few cents. It adds up significantly over time which is why they'd be willing to pay in the first place.
