The price of gasoline in ANY STATE is far far more than 9 cents.. Government makes more money on taxes from "ENERGY" of ALL forms than the producers do.. FOR DOING LITERALLY NOTHING..
Please read my post again. You'll see that I wrote that the price of gasoline in Kansas is 5 to 9 cents a gallon MORE that in Missouri. That difference is due to a difference in the gasoline tax. It has nothing to do with transportation costs. Stations owned by the same company, less than 1 mile from each other on opposite sides of the state line have a price difference of up to 9 cents a gallon.
