I would suggest that AI tech will open up more arbitrage opportunities for retailers as their price strategies come under pressure from inexpensive monitoring and reporting. Already I’ve worked on prototypes where shopping lists are fed into the system and the retailer that would give you the lowest price nearby is suggested.

Imagine the optimization possibilities where you have shared borders like you’re talking about, or where digital intelligence can be injected to optimize purchase prices among consumers for larger ticket or recurring items.

A lot of room for new and better strategies here.
