Amazon is rolling out an instant pickup service in several locations (expect Whole Foods to be on the list once the two companies are fully integrated). “Shoppers on Amazon’s mobile app can select from several hundred fast-selling items at each site, from snacks and drinks to phone chargers. Amazon employees in a back room then load orders into lockers within two minutes, and customers receive bar codes to access them.” (Before you know it, you’ll just be able to walk into a store and instantly buy a product and bring it home!)
