Amazon recently announced a new shopping experience that isn'tburdened with checkout lines. Shoppers download the Amazon Go app,scan their phone at the door and grab each item they want. Whenthey're ready to leave, they simply walk out of the store, view adigital receipt, and carry on with their day.

Amazon Go will initially launch in a single Seattle location,but knowing Jeff Bezos' vision to create “an everything store,” theretail giant is certain to expand well beyond that location.

The implications for grocery chains are obvious. They'll need toreplicate the Amazon Go experience just to keep up. After all, onceshoppers get used to skipping checkout lines, they won't go back.The experience of buying groceries is set to change forever.
