With the rising price of gasoline and the fact that a motorhome doesn't get too far on a gallon of gas, it pays to try to save on fuel in any way you can.

One way we have found is to get a gas rebate by using the Platinum Discover Gas Card. The terms seem to be changing rapidly, but the current deal seems to be a 5% cash rebate on the first $1500 of gas purchased, 3% rebate on the next $1500, and 1% from then on. There is no annual fee for the card, but be sure to pay it fully each month because the interest rates are exorbitant. I've set up an automatic deduction from my bank account to pay this bill when it's due, so I can be on the road and not worry about missing a credit card payment.

If I could do it again I would have gotten one card in Lolo's name and one in my own so that we would have twice the rebate capacity instead of getting one card with both our names on it.

There are other cards with similar offers, so if you use a lot of gas and have a decent credit rating, it might make sense to get some of these cards and just use them until the annual rebate level is reached.

We also have a no annual fee AT&T Visa card that offers 3% cash rebate on groceries and pharmacy purchases, and a Bank One card that gives 1% back on all other purchases. (Update - We were cancelled by the Visa card that gave 3% back on groceries. No reason was given, but since the card was paid by automatic electronic funds transfer, and we only used it for groceries, I assume they realized that it was a money losing proposition for them.)

Like everything, the fine print changes, and some of this may just be teasers to entice you into using their card. Fiscal discipline is required to avoid any nasty surprises.

The Flying J Rewards card is not a credit card, but a membership card that gives you a little off every gallon of gas bought at a Flying J. I believe its discounts are tiered and you would get a greater discount with a greater volume of monthly purchases. Since it's free, and the Flying J's are usually the best gas price anyway, it doesn't hurt to get this card. Flying J's are great for RVers anyway. They have RV islands to gas up, dump, fill up water, fill up the tires - and then they let you sleep in the parking lot if you've got no place better to go.
