I could only see this working if they straight-up close the store when the prices are adjusted or eventually maybe forcing shoppers to use carts/baskets with digital price tallies that you gotta' like press a button on each price display as you grab items or something. I don't know, a physical store with actual space and people is so much harder to rig like this than a digital storefront, I don't know if you can mesh them in a way that doesn't destroy any benefit for shopping in-person and I don't see how if the prices are raised enough it doesn't become beneficial for people to hire someone poorer for minimum wage to buy their groceries for them.
