I'll share this here now that I only drive EVs, but I suppose cashiers and random people at King Soopers(major grocer in Colorado, associated with Kroger's) would enter 555-555-5555 as their phone number for their rewards, and every time I would pump gas at their stations I would get $1/gallon off.

That number also works at Walgreens (at least in Arizona and New York).

What is the NPA for?

I meant bank card

Jenny left her number in your neighborhood too?

I largely thought this wouldn’t work, but having tried it at several grocery store chains while traveling with a 100% success rate so far I’m not complaining. (Nothing worse then being told you can’t sign up because customer service is closed, and you have to sign up to get the pricing, and there’s no generic store card they can scan as a curtesy ).

- this has worked for me in Rhode Island, Connecticut, Virginia, West Virginia, Michigan, and Wisconsin.
