Manager Jim Duke at a Dill Food Market says that grade of gas was supposed to be selling for $3.89 a gallon.
Duke says the "pump malfunction" involving a misplaced decimal point was fixed by Wednesday afternoon.
Nobody reported the mistake, which WOAI-AM reports apparently started Tuesday afternoon.
Duke says he noticed a lot of vehicles were being filled with premium and people were paying at the pump. He went out to check Wednesday and noticed the price error.
Duke says the independent gas station lost a lot of money. Just how much is still being tallied.
