Did you know that you can get an RV Fuel Advantage card and sign up at Flying J/Pilot and when you use the card you get a gas price discount of 2 cents a gallon and 5 cents a gallon diesel and propane of, I think, 10 cents and $5 off dumping fee.... Not much but it all helps out. I don't know how the diesel works but there was some talk on one of the other forums and it is possible that you have to do cash for the diesel. The gas you can use credit/debit card. Insert the credit/debit card, the insert the 'loyalty' card and after it pumps and give you the receipt it shows the discount. I know that not all Flying J/Pilots are easy to get in and out, but I use them a lot when on the road, because you normally can get a rig in and out. NOTE: Normally, not always.
Did you know that you can get a WalMart Gift card and it gives you anywhere from 3 cents a gallon to, get ready, today I got 10 cents a gallon off when I filled Herbie. Don't know if that is a today only, or if it has to do with the big signs in the store saying, get a WalMart card and get 10 cents a gallon off at participating stores. So I expect that I might fill Bunkie up at the local WalMart in the morning before I head off to Houston. I usually have a WalMart gift card that I carry around for fill ups.
In Texas the HEB stores also have a 'discounted' gas station and if you have a card and buy xxx dollars of grocery products you get xxx cents more off. I don't count those 'buy and get more cents off' as real discounts as a full-timer, that ain't gonna happen in a long time.
In Arizona the Safeway, Albertsons and Fry's stores have the same deal as HEB. The gas is usually comparable in price at those stations to the local Valero as they compete for customers.
Okay, that's my 2 cents worth....pun intended.
