Get 40¢ Off Per Gallon Today Only with Circle K Fuel Day

If you need gas today, don't pay full price.

Circle K just dropped a massive one-day promotion for Thursday, July 9. For the entire day, drivers can score an instant 40 cents off every gallon of gas as part of their Inner Circle Fuel Day celebration.

You don't need a complicated coupon code or a specific credit card to get this discount—you just need to be a member of their free rewards program.

The best part? If you aren't a member yet, signing up today gets you an extra bonus.

New Inner Circle members automatically receive 25 cents off per gallon on their first five fill-ups.

Note: This welcome offer doesn't stack with today's 40-cent promo. Circle K will automatically apply the bigger 40-cent discount today, and bank your five 25-cent discounts for your next five trips to the pump.

Here's everything you need to know to get the deal today.
