For grocers, the store's opening heralds another potential disruption at the hands of the world's largest online retailer, which bought high-end supermarket chain Whole Foods Market last year for US$13.7 billion ($18.1 billion). Long lines can deter shoppers, so a company that figures out how to eradicate wait times will have an advantage.
(Jan 22): Amazon.com Inc will open its checkout-free grocery store to the public on Monday after more than a year of testing, the company said, moving forward on an experiment that could dramatically alter brick-and-mortar retail.
The Seattle store, known as Amazon Go, relies on cameras and sensors to track what shoppers remove from the shelves, and what they put back. Cash registers and checkout lines become superfluous - customers are billed after leaving the store using credit cards on file.
