Amazon's no-cashier store can't handle more than a few shoppers
I use to would not go anywhere but Hardins for my medicines and everybody was friendly but now I don't recognize anybody there and they can be quite rude at times now and I can't even go in the store anymore because my wheelchair will only go as far as the check out counter up front. There is not a single place in there for me except 4 feet inside the front door.

And, more crucially, the tech is aimed at helping it fight back against rivals like . At the same time, in a sign that sometimes retailers need a quicker payoff from the tech they invest in, Target last month — a prototype for a small-format Target store it was building featuring robots, because, as Target CEO Brian Cornell explained at Shoptalk, he wanted to make sure" all of our innovation dollars are providing benefits in the near term."

As Walmart puts it, these startups will be sheltered from Walmart itself so they can grow and try things out without the pressure of being part of the world's largest retailer.The new look doesn’t scream facelift or flagship — by design.
