Postmaster general: Postal Service seeks revenue sources beyond regular mail, package delivery

The nation's new postmaster general says the Postal Service is looking beyond its regular mail and package delivery for new sources of revenue.

And that means building on what Megan J. Brennan calls its "core competency" — the delivery of goods.

The Postal Service is testing grocery delivery in San Francisco and delivering cases of drinking water to customers in parts of New York City.

During the 2014 holiday season, it joined with Amazon to deliver packages and expand Sunday deliveries of them.

The 52-year-old Brennan — the first woman to be postmaster general — is easing into her first days on the job.

She's a 29-year veteran of the Postal Service who started her career as a letter carrier in Pottsville, Pennsylvania.
