NO CHECKOUT NEEDED: AMAZON OPENS CASHIERLESS GROCERY STORE

Amazon wants to kill the supermarket checkout line.

The online retailing giant is opening its first cashier-less supermarket, where shoppers can grab milk or eggs and walk out without waiting in line or ever opening their wallets. It’s the latest sign that Amazon is serious about shaking up the $800 billion grocery industry.

At the new store, which opened this week in Amazon’s hometown of Seattle, 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.

“I love the convenience of literally grabbing and going” said Art Kuniyuki, a payroll and benefits manager from Seattle, who spent $15 on Barilla pasta, Dove chocolate and other groceries shortly after the store opened.

Called Amazon Go Grocery, the new store is an expansion of its 2-year-old chain of 25 Amazon Go convenience stores. It’s 10,400 square feet — more than five times the size of the convenience stores — and stocks much more beyond the sodas and sandwiches found at Amazon Go.

Cameron Janes, who helps oversee Amazon’s physical stores, said the technology had to be tweaked to account for how people squeeze tomatoes to test for ripeness or rummage through avocados to find just the right one. Nothing at the store is weighed. One blood orange goes for 53 cents; a banana is 19 cents.
