The regular mail may not run on Sundays, however, if you order from Amazon, your orders will now be shipped seven days a week.

The United States Postal Service recently partnered with Amazon to allow the delivery of their packages on Sundays. That’s right, the same group that wanted to quit working on Saturdays, will now be working on Sundays. The deliveries started yesterday in the major cities such as Los Angeles and New York. The company is hoping, by next year, that the program will extend further across the United States. The agreement is an NSA (National Service Agreement), which is defined on the USPS website. “A Negotiated Service Agreement is a contractual agreement between the U.S. Postal Service and an individual company that provides customized pricing incentives or other arrangements justified by a shift in the company’s mail operations. NSAs are intended to meet the needs of specific customers for whom mail is an integral part of their business strategy.”

The delivery rates for Sundays will not increase, but will remain a standard rate. However, Amazon Prime members will be able to get their deliveries for free. The packages will not come from Fed Ex or UPS, but will arrive from the USPS itself.

“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,” Dave Clark, Amazon’s vice president of worldwide operations and customer service, said. “We’re excited that now every day is an Amazon delivery day and we know our Prime members, who voraciously shop on Amazon, will love the additional convenience they will experience as part of this new service.”

The USPS also released a statement about the new Sunday deliveries. “As online shopping continues to increase exponentially, the Postal Service is very pleased to be able to offer shipping solutions that allow major mailers and customers alike to appreciate the benefits of using the U.S. Mail,” Postmaster General Patrick R. Donahoe said. “By offering Sunday delivery, the Postal Service is focused on serving the needs of our valued customers in today’s busy online world. We consider this a win/win for both organizations and are excited to be delivering packages seven days a week in select markets.”
