Amazon (AMZN+0.88%) Subscribers pay for it Prime in exchange for free two-day shipping, discounts on services like Grubhub, and access to movies and TV shows on Prime Video. Now you can add gas savings to that list.

Amazon announced Wednesday that Prime members can now save $0.10 per gallon at about 7,000 BP partners (B.P-0.03%) gas stations across the country, including Amoco and Ampm.

According to Amazon, this could mean an annual savings of nearly $70 for the average U.S. driver. Amazon Prime memberships start at $14.99 per month or $139 per year.

“We’re always wondering how Prime can save our members more money, and fuel savings is our latest offering that brings money back to members,” the e-commerce giant said in a Blog post announces the advantage.

Amazon added that it plans to extend these transportation-related savings to electric vehicle drivers in 2025 with an electric vehicle charging savings offer at BP Pulse, BP’s electric vehicle charging division.

How does it work?

To unlock $0.10 off per gallon, Prime members must have an account with Earnify, a Gas loyalty program from BP. Subscribers will then have to stop by a site set up by Amazon to activate the offer and link your Amazon account to Earnify.

Members can use the Earnify app’s store locator to find nearby BP, Amoco or Ampm gas stations. To redeem the offer, members must enter their phone number or linked payment method at the pump. Or they can use the Earnify app to select the station and pump.

Behind the deal

BP and Amazon publicly began working together in late 2019. BP announced this at the time delivery to integrate renewable energy into Amazon Web Services (AWS) data centers in Europe, while Amazon announced that BP would do so hike Data to AWS. In each announcement, the companies referenced BP’s environmental efforts.
