If you're an Amazon Prime member with a road trip on the calendar this weekend, there's a fuel discount worth grabbing before it disappears. From July 2 through July 5, 2026, Prime members can save 50 cents per gallon on a single fill-up at participating bp, Amoco, ampm, and Thorntons stations. That's five times the 10 cents per gallon Prime members get year-round, and it stacks neatly with the right rewards credit card.
Here's how it works, who qualifies, and how to squeeze even more value out of it.
How the discount works
The deal is tied to Amazon's ongoing partnership with bp's loyalty app, earnify. Normally, linking your Prime account to earnify gets you a baseline 5 cents off per gallon, plus another 5 cents for being a Prime member, for a standing discount of 10 cents per gallon at over 7,500 participating stations nationwide.
For the holiday weekend, Amazon is layering on an extra 40 cents, pushing the total to 50 cents off per gallon. The promotion applies to active Prime, Prime Access, and Prime for Young Adults members, covers all fuel grades, and has no minimum or maximum gallon requirement. It's good for one fill-up during the four-day window.
To use it, link your Amazon account to earnify through amazon.com/fuelsavings, or download the earnify app for iOS or Android. At the pump, enter the phone number tied to your account, or pull up the discount in the app, and the savings apply automatically.
The trick most coverage is missing: double it with Amazon Family
If you've got a household member linked through Amazon Family, you can double your savings. Each Amazon Family member needs their own separate earnify account, but once that's set up, each person gets their own 50 cents per gallon fill-up during the promotional window, which means two transactions worth of savings for one household. On a typical 15-gallon fill-up, that's the difference between saving $7.50 and saving $15.
Pick the right card to stack rewards on top
You'll still pay with a credit card at the pump, so it's worth using one that earns extra rewards on gas purchases rather than a generic card. A few options worth keeping in your wallet for this trip:
The Blue Cash Preferred Card from American Express earns 3% cash back at U.S. gas stations and transit with no cap, on top of its standout 6% rate at U.S. supermarkets.
The Wells Fargo Autograph Card and its premium sibling, the Wells Fargo Autograph Journey Card, each earn 3 points per dollar at gas stations and EV charging stations with no annual fee on the base card.
If you're carrying a Costco membership, the Costco Anywhere Visa Card by Citi earns an outsized 4% cash back on eligible gas and EV charging purchases, up to $7,000 spent per year.
For a points-earning option with strong transfer partners, the U.S. Bank Altitude Connect Visa Signature Card earns 4x points per dollar on travel and at gas stations.
Combine any of these with the 50 cent Prime discount, and you're effectively double-dipping: one savings layer at the pump, another in rewards on your statement.
Should you bother for one tank of gas
Honestly, yes, if you're already a Prime member and already planning to drive somewhere this weekend. Linking your account takes about two minutes, the discount applies automatically once you do, and there's no downside if you forget to use it; the everyday 10 cent discount just kicks back in afterward. It's not worth signing up for Prime solely for this promotion, but if you're already paying for the membership, this is exactly the kind of small, easy win that adds up.
