Surprised this hasn't happened sooner, IMO Google controlling the online UX/AI for products sourced from brick and mortars is the only viable e-commerce competitor to Amazon's continued dominance.

I'm a happy Amazon customer so I wouldn't switch, but as it's always healthy to have competition, I'd be a customer of both.

Either way handing over the user-facing UX to a major tech company doesn't bode well for the long-term future of Brick and Mortars as Google's brand will only become stronger with consumers who'd be a front for their suppliers that are ruthlessly competing in a war for the lowest price.
