I pulled up to the pump at Shell station and the sign read 2.73 for a gall on of gas. I went to the pump to get gas and the pump said 3.07 for a gallon. I asked the attendant in the store about it and he said that it was for cash or shell card only. It's very deceiving and most people wont' even notice the price when they pump it for 3.07. I told him it's not right and left, but needed a buyer beware. Even if the gas was for cash or shell card only, it needs to say and not up the price so much (34 cents a gallon) if credit is used. I went down the street for a usual price of 2.69 with no gimmicks. No station should be that different in the same area. 2.69 versus 3.07
