(Gray Media) – Gas prices may be at their lowest level since 2021, but Amazon Prime members can save $1 per gallon for up to 35 gallons at select gas stations this Fourth of July holiday weekend.

Prime members can link their accounts to BP’s “Earnify” rewards program to get the deal at participating Amoco, BP and AM/PM gas stations nationwide.

According to Amazon, the $1 off per gallon is valid for one time use on the next fill-up available from Thursday, July 3, through Sunday, July 6, ahead of Amazon’s 11th Prime Day, which officially starts July 8.

“An Earnify account is free to create and automatically applies 5¢ savings as a baseline offer, 5¢ savings for Prime members, and an additional 90¢ savings during the promotional period to total $1 off per gallon during this promotional period,” Amazon explained in a news release.

Once the promotional period is over, Prime members will still be able to access a total of 10 cents off a gallon at participating stations through the Earnify account.

According to GasBuddy, the national average for a gallon of regular unleaded is $3.15.
