It is about the e-ink labels. I don’t disagree that companies like Walmart will use it to be scammy, but I believe all companies should switch to those. I also believe there should be laws against dynamic pricing to avoid this type of issue.

When I worked in retail, we would have a team of 6 spend 4 hours going through the entire store to swap out every single price tag before the store opened. It didn’t matter if the price stayed the same because the tags had expiration dates and customers would get their panties in a bunch over it. The amount of plastic waste created by weekly and daily price changes is insane.
