Amazon already has lockers in various public locations that you can use to receive packages, but it's now offering a more private option for multi-tenant dwellings. The e-commerce titan has launched a new service that offers to install "Hubs" in condos, apartment buildings and complexes for use exclusively by people who live there. Once it's installed, Amazon doesn't care who uses it for delivery -- you can use it to receive parcels from other websites, retailers and even from your relatives.
