IF you have the rewards card AND you've registered it here's the procedure:
Pull to the pump and swipe the rewards card.
Pump will check the card and authorize "Pump Start".
Pump your fuel. When done, go inside to pay.
You will be charged the cash price less 3 cents a gallon.
If you've not registered your rewards card, then you must go inside before you can pump.
Remember the rewards card will only be valid for a few more months before the Good Sam Swipe and Save card takes its place. You can also get the RV Plus card which will save you 6 cents a gallon but you cannot use a separate credit card for your purchase....Dennis
