I California you pay the lower of the shelf / ad or as rung.
Note: paper shelf tags also have the PLU code to invalidate simple tag moving.
Weights & Measures does pop 'scanner' inspections. They scan the item with their test gun, key the price from the label. This prints both on a paper tap, that they then use to ring up at a cash register (they also choose the lane if more than 1).
There are fines for over charges detected (they might RED TAG the store if there are too many).
