I'm curious as to why aside from Sam's Club and the Flying J truck stop generally being a few cents less, there is never any variance in Grand Forks for gas, but there can be as much as 47 cents per gallon difference between stations, at least as of yesterday, for diesel? Why wouldn't the "agreement" on a set price for gas, which circumstantial evidence strongly suggests has existed for years in GF, extend to diesel, as well?
