Why wouldn't I give an answer? Or were you just trying to be a smart ass? Honest answer is 5-7 cents per gallon. And with the amount of competition anymore its closer to less than 5 cents. As stated above the walk ins is where most places make their money in the convience deparment. Sorry if that is plowing you but don't blame us. We aren't even close to being the middle man, actually we are the end man and we get the satisfaction of getting accused of gouging the shit out of our customers. Im sure there are some shady stations out there but we aren't one. You wanna be pissed at someone you pay 46.4 cents a gallon in tax alone.
