Prepaid Gas

Can anyone tell me where can I get the prepaid gas cards at a discounted rate because I am trying to control the budget on gas and other expenses like food and hotel.

I found a notice on prepaid gas cards at reduced prices http://www.reviewsavenue.com but I do not know if the composition of prepaid gas is a program of confidence to join or not.

prepaid gas cards really do not do too much because gas prices can vary from anywhere. If you travel from one state to each state to impose their own taxes on fuel, you can lose money on your prepaid card. Better to budget as much as do BP, Shell, Texaco transported. Your best bet is to buy gift cards Wal-Mart and I buy gas at Wal-Mart, you get a discount on every gallon of gas purchased.
