guttentag writes "The New York Times is reporting The USPS has struck a deal to deliver Amazon's packages on Sundays — a first for both. The Postal Service, which lost nearly $16 billion last year, often loses money on first-class mail delivery, but package delivery is profitable. The Postal Service said it expected to make more such deals with other merchants, seeking a larger role in the $186 billion e-commerce market. For this holiday shopping season, Sunday delivery of Amazon products will be limited to the Los Angeles and New York metropolitan areas. In 2014 it is expected to expand to other cities including Dallas, Houston, New Orleans and Phoenix."
