U.S. Postal Service Wants to Deliver More Groceries

The U.S. Postal Service wants to expand and extend its test of same-day grocery deliveries but isn't ready yet to take the venture nationwide.

The agency asked the Postal Regulatory Commission on Friday to extend the two-year test for another year, to October 31, 2017, and for permission to enter new markets. The venture serves select ZIP codes in the New York, Los Angeles, San Diego, Sacramento, Stamford (CT), and Las Vegas areas — mostly in partnership with Amazon's "AmazonFresh" service.
