How do you shop at Kroger 🤷‍♀️ lol

Growing up, I only went to Kroger a handful of times, and have never been there since then. To me, it's a "weird" store. That and Marsh. We just never did our shopping there.

I do remember the few times we went, my mom had a Kroger card. Do you have to have a Kroger card to shop there? What does the card do?

Someone posted that they have a good sale on something I want, so I don't want to go in there and look stupid lol. I would rather anonymously look stupid on here!
