Circle K Offers 40¢ Gas Discount for Inner Circle Members Nationwide August 21

Circle K is offering a 40-cent discount per gallon of gas on Thursday, August 21, 2025, as part of its Inner Circle Fuel Day promotion to help ease back-to-school financial strain. The discount is available from 6 a.m. to 11:59 p.m. at over 4,000 participating Circle K locations across 22 states and is applied automatically at the pump when Inner Circle members enter their associated phone number. New customers can join the Inner Circle loyalty program via the Circle K app or website to access this and ongoing fuel savings, including a 3-cent daily discount and an upgraded 5-cent discount after spending $500. This promotional event has been held multiple times over the past year, often coinciding with holidays, but the August 21 deal is not tied to any specific holiday. Circle K emphasizes its commitment to supporting communities by providing value through these promotions during financially challenging times. Customers can verify participating locations and program details on Circle K’s website or mobile app.
