How to Stack Gas Rewards on American Express for Free Gas

We just filled up our Durango with $75 in free gas, courtesy of the ability to stack the purchases on our Blue Cash Preferred® Card from American Express [1] card.

You should have seen the look on the cashier’s face just a few days earlier when she reported how much free gas we had earned!

I think it’s been a few years since I had a credit card that I was so in love with, but the ability to stack it with other promotions is quickly making it my favorite credit card this year!

Gas Rewards

Our grocery store participates in the fuelperks [2] program. I’m guessing you probably know how it works if your grocery store has a gas rewards program since they are pretty popular. Essentially, we earn 5 cents off a gallon of gas for every $50 in purchases.

We spent $3750 at the grocery store last month and earned $3.75 off per gallon. At 20 gallons of gas, we got $75 in free gas!

Now we all know that I didn’t spend that much on groceries [3] last month. It was more like $250 on groceries and $3500 in Visa gift cards.

I thought for sure that the grocery store wouldn’t allow you to earn gas rewards on gift card purchases, and I think it states that it specifically excludes them, but the registers are programmed such that you earn them!

Doing the Math

Here’s the breakdown on the total cash back earned stacking all the rewards:

  • Purchases: $3500 in Visa gift cards
  • Fees: $41.65
  • Gas Rewards: $70
  • Envaulted [4] Cash Back: $43.75
  • 6% American Express Cash Back: $212.50

Effective Cash Back: 8.13%

Stacking the Blue Cash Preferred® Card [1] with gas rewards and Envaulted almost doubled the amount of cash back I originally planned on earning when I got the card.

Purchasing Gift Cards

For more information on buying gift cards with the American Express card, you can read the introduction on the American Express 6% Cash Back Credit Card [5].

We’re using the gift cards to pay real estate taxes, but if you don’t have a need for the gift cards, you can find out how to Empty Your 6% Cash Back via ATM and Cash Advance [6].

Other Gas Perks

In addition to fuelperks which serves Roundy’s, Bi-Lo, Martins, and Winn-Dixie, one of our experts on the American Express Blue cash back, reader Barbara checked into the gas rewards program at Safeway:

  • Safeway is giving 4X the number of points on gift card purchases until December 10.
  • Safeway does NOT give gas rewards for the Visa Prepaid cards.
  • Each 1000 points equals $1 off per gallon of gas at Safeway stand-alone gas stations.
  • There is a limit of $1/gal off at each fill-up.

And another reader checked out Shop n Save:

  • A purchase of 2 $500 gift cards earned 2 $5 off fuel card coupons (for when you buy $100 or more in fuel gift cards).

When we head south for the holidays, I’ll also check into the Kroger gas program and see if that one is working.

Homework Assignment
