Circle K is holding an event on Thursday, January 15, offering customers 40 cents off per gallon of fuel at more than 5,000 stores. The event, called Inner Circle Fuel Day, will run from 12:00 a.m. to 11:59 p.m. local time in the United States.

“Every dollar matters—especially as customers recover from holiday expenses and look for ways to start the year off with smart savings,” said Louise Warner, Executive Vice President of Operations, North America, for Circle K. “Fuel Day is our way of giving back and rewarding Inner Circle members with meaningful savings on something essential.”

The offer is open to all members of Circle K’s free rewards membership program, Inner Circle. It’s easy to take advantage of, too. To unlock the 40 cents-per-gallon fuel discount, all members just need to enter the phone number associated with their account at the pump or at checkout.

The Circle K deal on gas comes at an interesting time. GasBuddy projects that gas prices will fall below $3 per gallon this year. That would make it the fourth consecutive annual decline and the lowest national average for gas prices since 2020.

However, analysts project that the national gas price average will briefly rise into the low $3.20 range in the spring. They then predict that gas prices will decline steadily to near $2.80 per gallon by December.

“There’s still a tremendous amount of uncertainty over the regime and a few Maduro loyalists left in Venezuela running the government,” Head of Petroleum Analysis at GasBuddy Patrick De Haan told Forbes. “If there are a lot of pieces of the regime left over, especially with oil prices already at multi-year lows, there’s not much incentive for U.S. producers. There’s still a tremendous amount of risk.”
