If you missed out on this OnePay fuel deal, then Circle K has another opportunity for you tomorrow.
Circle K is bringing back Inner Circle Fuel Day on Thursday, August 13, 2026, giving members 40 cents off every gallon of fuel all day at participating locations across the United States. The promotion runs from 12:01 a.m. through 11:59 p.m. local time.
