Amazon.com  unveiled a new partnership with the U.S. Postal Service to deliver  online orders from the world's largest Internet retailer on Sunday for  the first time.
The service started this weekend in the Los  Angeles and New York metropolitan areas and Amazon plans to expand it to  a large portion of the U.S. population in 2014, including Dallas,  Houston, New Orleans and Phoenix.
Amazon is not charging extra for  the new service, so members of the company's popular Prime service will  be able to buy products on Friday and get them by Sunday for free. The  service also applies to non-Prime members, who can get free five to  eight-day shipping on orders of at least $35 (up from $25 previously).
Amazon  has been spending billions of dollars building new warehouses around  the world so it can deliver products more quickly. The company hopes  that adding Sunday as a delivery option will generate more sales.
"The  three big pieces of growth for us are selection, lower prices and  speed," said Dave Clark, vice president of worldwide operations and  customer service. "Adding an additional day is all about delivery speed.  An Amazon customer can order a backpack and a Kindle for their child  and be packing it up on Sunday for school on Monday."
The deal is  also a welcome new source of revenue for the financially struggling U.S.  Postal Service, which has been trying tap into the growth of online  shopping.

"It  will certainly help. The fastest growing segment is the package  business," Postmaster General Patrick Donahoe said. "The future of  package delivery is a seven-day-a-week schedule. We've got the capacity  to do it."
The postal service expects to deliver 420 million  packages this holiday season, a 12% increase over last year, but it is  in a precarious financial condition. The organization lost $15.9 billion  in its last fiscal year and expects a loss of $6 billion this year.
In  September, the postal service said it would seek to raise the price of a  First-Class stamp from 46 cents to 49 cents. That price hike, which  would kick in Jan. 26,  and increases for postcards and international  mail would generate $2 billion in revenue, it said.
Amazon is  increasingly delivering its own packages, through new services such as  AmazonFresh, its online grocery business. The company will also start  delivering packages itself in some parts of London in coming weeks,  Clark said.
However, the company still needs carriers such as  USPS, United Parcel Service and FedEx to help it cover the so-called  last mile to most people's doorsteps. And the USPS is the only delivery  service that reaches every address in the nation – 152 million homes,  businesses and post office boxes.
"We are leveraging our  technology and infrastructure to get packages to USPS so they can create  an incremental day of package delivery," Clark said. "This helps them  and it helps our service too."
