Amazon's business is built on three basic concepts: faster delivery, greater selection, and cheaper prices.
In service of that, it has built enormous warehouses staffed largely by robots that shuttle around, pulling goods out of bins at remarkable speed. It can take just a matter of minutes to go from order to shipment.
And lately it's pursuing a program where Amazon goes directly into manufacturers and manages their logistics and online retailing.
After Hurricane Sandy, the south shore of Staten Island looked like it had been hit by a tsunami. The storm surge devastated whole neighborhoods suddenly, in a matter of hours. In the year since the storm, some families have been rebuilding their homes and their lives. Others are ready to sell their flood-damaged properties and move on.
