I received a flyer in the mail last night for the new Flying J Mastercard. Didn't think much about it until I started reading the flyer. It indicates that effective September 1, 2008, the only way to get the cash price at the truck diesel pumps is by using the FJ Mastercard. The RV Card will get you a 1 cent discount or more (up to 4 cents per gallon with a 300 gallon limit per month) depending on how much you spend inside the store, but not the cash price (as I read the flyer). The card does indicate no annual fee "ever". It looks like to keep the bus running on cheaper fuel it is time to get the FJ Mastercard. Based on our average miles per year resulting in about 3K gallons of fuel thats a savings of $200+ per year based on the credit upcharge of 7 cents per gallon. I wish they could just leave the RV card as is.
