Dollar-stores overcharge customers while promising low prices

“In one court case in Ohio, Dollar General’s lawyers argued that “it is virtually impossible for a retailer to match shelf pricing and scanned pricing 100% of the time for all items. Perfection in this regard is neither plausible nor expected under the law.””

Sorry—-what? Isn’t that one of the fundamental basic jobs to be done and expectations of a retailer? You put physical things on display for sale, you mark prices on them, and you sell them. When the prices change, you send one of your employees to the appropriate shelves and you change the tag.

When on earth did we get into a world where that absolutely fundamental most basic task is now too burdensome to do with accuracy?

An easy test for this is how often the price at the register is higher vs lower than the marked price. If it's close to 50%, then ok, it's a mistake. But if it's higher...

I don't think you would reasonably expect it to be close to 50/50. Most price changes are increases and the mistake theory basically boils down to the employees never updating the shelf tags. Which I think is an extremely plausible theory since the one employee at the store isn't paid enough to bother. And who's even going to check that they updated the tags? Dollar General isn't shelling out money for that.

There's another kind of store that's in a similar situation: thrift stores and nearly all of them have also decided this problem is too hard. Lots of items are marked with just colors based roughly around their estimated value and the store changes the price/color mapping occasionally.
