Prime members are eligible to save 20¢ per gallon when refueling on every Friday through May 29. You'll need to swing by any bp, Amoco, or a participating ampm or Thorntons to get the savings. First, you'll need to link your Amazon Prime account in the Earnify app and enter your phone number. After that, you'll be able to use the app to save 20¢ per gallon once every Friday. If you need to refuel any other day of the week, you'll get 10¢ off per gallon as a Prime member.

Keep in mind this is valid only for U.S. Prime members and you can only use the discount once every Friday, so you won't be able to fuel up vehicles for the entire family. Amazon mentions 7,500 gas stations are participating in this deal, so there should be one fairly nearby your home.

Since this deal is valid through May 29, you still have eight Fridays to refuel with while saving 20¢ per gallon. If you're already a Prime member, there's good reason to take advantage of this savings.
