There are certain expenses in your budget you may be able to eliminate, like streaming services or meal delivery kits. But putting gas in your car is an expense that’s unavoidable.

If your tank is empty and you need your car to get to work, it’s a problem. So if you rely on your car to go places, you have to fork over money for gas, no matter what.

But if you’re an Amazon Prime member, you’re in luck. Thanks to a new benefit, you may be eligible for big savings on fill-ups.

A very welcome perk

Amazon Prime costs $139 a year, but in exchange, you get benefits like free shipping on orders of any size and access to streaming content. Now, Prime members can link their accounts to earnify™ and then use the earnify™ app to find fuel stations in their areas that offer a discount on gas.

All told, you’re looking at saving $0.10 per gallon regardless of the grade of fuel you purchase for your car. And that benefit doesn’t max out at a certain number of gallons, so if you drive a lot, you can save big.

Amazon says that Prime members can save almost $70 per year on fuel costs. When you look at it that way, you’re basically getting back half of your annual Prime membership fee.

Other ways to save money on gas

If you’re already an Amazon Prime member, you might as well take advantage of the option to save on gas. But if you’re not a Prime member and don’t think you can justify the $139 annual fee, you’re not out of luck. There are other steps you can take to lower your fuel costs.

Join Walmart+

For one thing, Walmart+ members can save $0.10 per gallon of gas at select stations as well. And an annual Walmart+ membership is only $98 per year, compared to $139 for Amazon Prime. Walmart+ also gives you free shipping for online orders, plus free grocery delivery with any $35 minimum order and access to streaming content with Paramount+.

Fuel up at Costco

Another way to save on fuel involves maximizing your Costco membership. Not only does Costco offer some of the cheapest gas in town, but its fuel is TOP TIER™ certified, which means it could lend to better performance.

Change your habits

Making changes to your driving habits could also result in fuel-related savings. If you have colleagues who live nearby, set up a carpool. And if your work schedule is flexible, play around with different off-peak commutes. If you’re not stuck in traffic day in, day out, you might burn through less fuel (plus, avoiding traffic could work wonders for your mental health).

Use the right payment method

Finally, be sure to swipe the right credit card when you fill up your tank. Check out this list of the best credit cards for gas rewards so you can earn extra cash back on fuel purchases.

It’s pretty neat that Amazon is offering savings on gas for Prime members. But there are also plenty of other ways to reduce your fuel spending — and add more money to your savings account instead.
