I once worked as a cashier at “The Fresh Market” chain, a higher end, higher income store. We had this issue all day every day. I couldn’t go a shift without having to call over the manager for two or three price corrections. The root-cause was our incompetent stoner stock-boy would leave up discounted sale signs up for days and even weeks after the time had passed. Despite his bad work ethic he worked there for years because help was just that hard to come by. Nothing ultimately malicious by corporate but the end result looks suspicious as can be.
I understand that- the key is "varying degrees". This article documents several cases across multiple states that go well beyond reasonable. I've learned to be careful to look at the dates on sale tags.
Another thing many grocery chains do is list a price that is only for folks who sign up for the stores tracking program, rather than the price that folk who don't want to jump through whoops and sing the song and dance pay. (They put that price in the fine print).
