Prepaid Gas Cards

Sometimes the way you pay can help save on gas. Discounted prepaid gas cards can sometimes get you a 10% savings. These cards are similar to debit cards, but are only good for the purchase of gas. You get one with a preset starting balance. The trick is that gas companies will offer incentives for buying these. Maybe you can get a balance of $55 paying only $50. That 10% savings doesn't look like much on each card, but 10% is 10% and over a year it adds up. Another advantage is that is helps you budget your gas use. If you give yourself one card, you know when it is gone. But if you pay for your gas out of your pocket, it can be difficult to notice where it all goes to.
