      Does the discount show as the advertised price or do you have to enter your rewards number first?

        Is the reward number your phone number? I can’t find a inner circle number

          Good question, Yvonne! Yes! I did find these details when logging in: Enter your mobile number at the pump or in-store. Happy saving! ❤️

        Hey there! Here’s what I found on this when searching – “To get the Circle K 40 cents off per gallon discount, you need to enter your phone number associated with your Inner Circle rewards account at the pump, and the discounted price will then be displayed on the pump; you don’t see the discount before entering your number.” Hope that helps!

    Ha! I had seen an ad or email for this deal yesterday for today, so i went to circle k this morning and asked about the promotion because I didn’t get the onlineplete details and the cashier said “no we aren’t having any $.40 off gas.” guess their employees aren’t informed. Just seen your post now so I’ll be headed back to circle k later 🙂 thanks for posting!

      You bet, Laura! 🤗 You might also click through the link in our post to verify that your nearest Circle K is participating, before making another trip. The discount should apply for you once you enter your details at the pump, if you wanted to give that a try as well. ❤️

    Yes your phone number is your membership number. I first tried it with the 1 then phone number. That didn’t work start with your area code.

    Has this worked for anyone outside of Illinois, Indiana, Kentucky, Ohio, Tennessee and West Virginia? When you click on the link in this post it says it’s only valid in those states.

    • Jessica (Hip Sidekick)

      I’m seeing those states listed as well, Ashley. ❤️ If you live outside those states and have a Circle K nearby, you might call them before making a trip to be sure they are participating. 🤞

    I stopped by this morning on my way to work, but our local station has a sign out at the register stating they do it NEXT Thursday.
    Question: does anyone know if there is a limit to how many gallons we can get? I am hoping my kids can get cheaper gas also by entering my cell phone number.

    • Jessica (Hip Sidekick)

      Hi Susie! Here’s the details on the limitations: At participating Circle K Fuel locations. Limit 35 gallons per transaction. One-time use only. Thanks for letting us know that your location is offering this discount on a different day. 🤗

    This appears to only be regional to northeast area. Even though it doesn’t state that on the site. if you look at the locations in the link for .40 off, it only shows a few states. Needless to say, didn’t work for me in central florida.

      It works in South Georgia (we just have it a week later) so maybe it’s just your location(s) that don’t participate!
