For those just wanting a summary. Nobody is updating the price tags on the shelf. So when you get to the register, it rings up at a higher price. And if you never look at your receipt then you'll never know you over paid.
It a lot of states it's easier to pay the fine than to hire someone to come regularly update the price tags. Error rates in most states are capped at 0.5% to 2%. However, in the example store they talk about in the story, the error rate was 23%. Which is wild. But given that the fine is just $5,000 per inspection, they're likely making more money in the long run.

That's really odd for a State that has regularly written off all the various pollution Musk does over at his launchpad. And of course that ignores the obvious anything and everything that has anything to with oil production there.
