I know the retail industry well, professionally. It is a low margin, high throughput industry, meaning that you want to tie in the customers as best as you can. The best tie in is price; Walmart, Kroger, Aldi, Target, Costco, they all fight for audience, in the end by lowering the price points. The most expensive “parts” in a store are the employees, and if you can reduce those numbers, you can lower your prices too. So the automation helps these retailers to keep the customers from wandering off to cheaper stores, while increasing the margins.
