Twelve years ago, Amazon launched Prime, a subscription service that entitled members to free two-day shipping in the United States.
Since then, it has added a number of options to make delivery faster and more convenient. Prime customers can get same-day delivery, and drop off with an hour or two on some items. Of course, customers aren’t always home to receive their packages. So Amazon started putting lockers in nearby convenience stores and building lobbies. It even showed off drones that could drop the package right into your backyard. Today it’s taking the obvious next step and introducing a service that will allow Amazon couriers to open your front door and put your package safely inside your home.
