No Checkout Needed: Amazon Opens Cashier-less Grocery Store Associated Press NEW YORK - The online retailing giant is opening its first cashier-less supermarket, the latest sign that Amazon is serious about shaking up the $800 billion grocery industry. At the new store, opening Tuesday in Seattle, shoppers can grab milk or eggs and walk out without checking out or opening their wallets. Shoppers scan a smartphone app to enter the store. Cameras and sensors track what's taken off shelves. Items are charged to an Amazon account after leaving. Called Amazon Go Grocery, the new store is an expansion of its 2-year-old chain of Amazon Go convenience stores. At 10,400 square feet, the supermarket is more than five times the size of the smaller stores, and stocks more items beyond the sodas and sandwiches found at Amazon Go. The new market stocks fresh baked bread, blood oranges, butternut squash and other food to whip up dinner or stock the fridge. Amazon is not new to groceries. It made a splash in 2017 when it bought Whole Foods and its 500 stores. It's also been expanding its online grocery delivery service. .
