Amazon Partners With US Postal Service for Sunday Delivery Sunday delivery now available in New York City and Los Angeles.

Nov. 11, 2013 -- Whether you're watching a football game, catching up on housework or recovering from Saturday night's shenanigans, there's a good chance that you'll be home Sunday afternoon. And now you can receive packages from Amazon on Sunday, thanks to the online retailer's partnership with the US Postal Service for Sunday delivery.

"As online shopping continues to increase, the Postal Service is very happy to offer shippers like Amazon the option of having packages delivered on Sunday," said Postmaster General Patrick R. Donahoe in a statement. "Customers can expect the same reliable and valued service that the Postal Service currently provides."

Kelly Cheesenan, a spokeswoman for Amazon, said that the partnership was a result of the company looking for new ways to make deliveries more convenient. "We know our customers definitely wanted Sunday delivery," she told ABC News. "And the U.S. Postal Service has been delivering to households for more than 200 years."

Sunday delivery service is available now for New York and Los Angeles customers, and will roll out to other cities across the country. Cheesenan said that the majority of Amazon users can expect Sunday delivery in 2014. "It will be available to customers at no additional shipping cost."

In addition, customers who have signed up for Amazon Prime will also be able to pair their free two-day shipping with Sunday delivery. "If you're an Amazon Prime member, you can order a backpack for your child on Friday and be packing it for them Sunday night," said Dave Clark, Amazon's vice president of worldwide operations and customer service. "We're excited that now every day is an Amazon delivery day."
