Key Points
Walmart is rolling out digital shelf labels and expects the technology to be in all U.S. stores by year’s end. Kroger also has begun experimenting with the technology.
The nation’s largest retailer says the digital price tags help associates do their jobs better and stresses that prices on items will be exactly the same for every consumer in every store.
Some legislators are wary of the technology’s potential to be used in dynamic pricing models that disadvantage consumers, with Sens. Jeff Merkley (D-Ore.) and Ben Ray Luján (D-N.M.) introducing a bill to ban it.



The problem is that you may have grabbed that item at its lowest point, and updated to a higher point by the time you get to the register.
Yeah, I’m not arguing with that, just with the claim that they update instantly. Never said anything about anything else, and don’t plan to :)
Gotcha, obviously laws are going to have to catch up to this. But in many places, it won’t.
