I use the card, I highly recommend it if you want to save decent money on fuel.
Last good trip i saved over $350.00 in a week.
Doubt me...?
Try it first.
The thing is now that we are deep into a world wide drop in the price of a barrel of oil, there can only be so much extra discount available.
So today you may only see about 45 to 60 cents off on a gallon depending on location.
It costs nothing to join up, and as long as you have a smart phone you will be able to save as much as can be saved, and be able to see any station along your route and what you will pay for fuel there....
