From Wikipedia
Amazon Go was a chain of convenience stores in the United States and the United Kingdom, operated by the online retailer Amazon. The stores were cashierless, thus partially automated, with customers having the ability to purchase products without being checked out by a cashier or using a self-checkout station. In 2023, there were 43 open and announced store locations in Seattle, Chicago, Los Angeles, London and New York City.
