On Monday, December 5, online retailing giant Amazon announced the opening of its first brick and mortar grocery store. Called Amazon Go, the Seattle-based store that is currently being tested by company employees, closely mimics regular convenience stores except for one thing — thanks to Amazon’s proprietary “Just Walk Out” technology, all purchases are handled electronically. This means there are no cashiers, checkouts, or lines. Shoppers simply grab what they need and leave.
