It think it's more helpful when exposing their fraudulent offers. An easy example was loyalty cards that had one purpose but were sold on the lie of big savings. A common trick was to inflate the "regular" price above what was common, offer a card-only "discount," and show the "savings" that came with it. It sounds like they're hooking you up until you go to... any... of the other large competitors seeing similar prices. Even worse, one in my area started adding "You could've saved X dollars" on their fake sales at the bottom of the receipt. It's stuff like that which might justify rules for transparent pricing. Then, consumers can just avoid companies playing a lot of games with them. Or choose or be stuck with them due to other reasons. This is just one tool in the toolbox.
