Strange how this totally worked until a few years ago. I never cut coupons or any other time wasting shenanigans, but was able to stop up on deals on the commonly used shelf-stable items I buy without even needing to signup to a loyalty program.

I understand price segmentation is a thing. But it's gotten pretty exhausting and only increasingly so.

Fast food you can simply opt out of. My health improved due to them shifting all the "deals" to the app, and doubling menu prices. Groceries are a different thing.
