Amazon has been plotting its next big move to control its ever-evolving logistics chain, with a new service called "Shipping with Amazon" in the works and reportedly scheduled to launch within weeks. It initially will pick up goods from third-party sellers that already work with Amazon and deliver them to customers. The service eventually will expand to merchants that currently do not work with Amazon. It will launch in Los Angeles and expand to other U.S. cities over time, and reportedly will undercut UPS and FedEx on price.
