Do you have to sign up for the Inner Circle membership or just pull up to the pump and the discount is automatically reflected at the pump without needing a code or membership id?

In my experience any time circle k has a fuel discount it’s only valid in store. I have a rewards card for $2.50 off every time I get gas there and that’s only valid inside. I also enter my phone number for their rewards program prior to scanning my gas savings card.

code needed outside of the promotional hours. Signing up is easy, and if you live near by a CircleK you also get 25 Cents off your first 5 fill ups (not onlinebined with this offer). You can uncheck the boxes that allow permissions for them to contact you with promotions during sign up.
