This could work in conjunction with a future "just walk out" checkout implementation. You see a price at the shelf, pick up the item, you're presented with a bill in your email. You can't claim the price changed on the way to the register, and they know what price they showed you.
They could do that with their shopping app that lets you scan an item and checkout in app; but as soon as people found out they were charged different prices for the same thing on say the same day it would be a PR nightmare. I can see it more as a way to adjust prices dynamically regionally based on demand, not much different than what is done anyway just faster.
