Supermarkets all throughout my country have these labels add "35% off" to any goods that they need to remove from shelves (either because they expire soon or because they want to replace the product with something different). That's done outside of normal advertising campaigns, just in the price tags on the shelves (and the digital systems, if they actually work).
Supermarkets here are already on thin ice because they frequently do not charge the price listed on shelves already, without malpractice.
Of course, if you happen to have a cart full of wrongly discounted stuff that someone needs to go out and correct, the store will probably look through security footage. If you play the game well and can make it look like a glitch in the system, a store would probably not bother, though.
