Flying J offers a rebate, something like a penny a gallon, if you're a registered member with them. It's not a "At the pump" kind of thing, you're sent a card/check at a later date. As best I can tell, they weren't sending the full amount to people. While it sounds like nothing, it can add up quickly. A truck burns about 500 gallons a week. $5 x 52. So it's only $260 a year. But multiply that by hundreds of thousands and it's a small fortune that JH saves.
