I don’t know about the rest of Canada, but in Quebec the label not matching the register is considered a pricing error and generally you get to pay the display price.
Merchants must sell items at the advertised or displayed price.
With digital labels, the displayed price and the register price will always line up.
EDIT: For some reason I thought this was a post in /c/Canada. Some states might have similar regulations though…


What I mean is that the displayed price and register are always in sync.
Realistically, I feel like it would mean that they can only change prices during shutdown hours (or perhaps VALID UNTIL prices for changing mid-day). Changing displayed prices manually each night is too much labour to be worth it, but with digital labels, it could be done.
More dystopian, I’m sure at some point Walmart will be able to track each person to display a unique price when they are looking, and that displayed price can follow them to the register.
