If you buy gas at Costco, then check out the True Earnings Costco Credit Card where you can use this for Costco gas purchases and earn 3% back. There is no limit on how much you can earn back with this card.

Based on today’s prices of 4.2 per gallon, lets say it takes you $84 to fill your tank. Lets also say you fill your tank 3x per month. This would total out to $252.

$252 x 12 months = $3024 per year.

Take the yearly total of $3024 and multiply it by your 3% cash back rate and you get a savings of $90 or one free tank of gas. If you only gassed up at BP and used the Chase BP Visa card, you could be saving $151 per year.

So if you want to save money on gasoline, use a gas cash back card and combat the high prices.

1. American Express Centurion (AKA the American Express Black)

The Centurion is the ultimate high-end card, with less than 10,000 issued worldwide. You can’t apply for the black card – it’s offered by invitation only.

The annual fee is $2,500 and you have to charge a minimum of a quarter-million per year. Besides being able to rub plastic with celebrities and fellow millionaires, what perks does the Amex Black give you?

The Starwood Preferred Guest program is one of the most advantageous credit cards to charge purchases on because of the ability to exchange Starpoints for either free airline tickets or hotel room nights. Plus you don’t have to worry about the airline you racked up all your miles with going out of business. Hotel chains are less likely to go away anytime soon in comparison with the recent bankruptcies we’ve seen in the airline industry.

The Starwood Preferred Guest Credit Card is a great Airline Card Too

I know it doesn’t make sense. A hotel rewards card that is ranked best airline card? Why? Well with some partner airlines,
members can transfer their Starpoints from their SPG account to an airline account and receive a 25% bonus. That right, a 25% bonus. So for every
20,000 Starpoints you transfer to say American Airlines, you will receive 25,000 Aadvantage airline miles.

Another reason frequent flyers love the Starwood card is because you can transfer Starpoints on a 1:1 basis with most airlines. Try that with other cards.
