Sadly, this article doesn't explain how this "surveillance pricing" (which is just a scarier-sounding synonym for "dynamic pricing") would even work in a physical grocery store.

This is often done in stores where they say that prices can change daily, and that these tools help them keep prices up to date. The darker pattern is what this law prevents, and that even with this sort of labeling, they can't charge you different from what they charge me in the same store.
