Was surprised at Sunday delivery by Amazon and USPS

The U.S. Postal Service is known for working through rain, sleet and snow, but not on Sundays or holidays, right?

That is changing, quickly, through a deal with Amazon. In many parts of the country, products ordered from Amazon now arrive at your home seven days a week, year-round. As GeekWire reported last week, the rollout is expanding nationally even faster than originally expected.

The change is catching some Postal Service customers off guard, who may find it shocking that an institution of its size can evolve the way it does business. On Twitter, one person said it’s “kind of like magic,” and another person called it a #pleasantsurprise.

As postal trucks start circling U.S. neighborhoods, and customers get knocks on their front door on Sundays, people have become more aware of the service, and naturally, questions have started to arise. So we put together this FAQ to answer some of the most common questions about Amazon’s Sunday delivery service via USPS:

How come I’m seeing mail carriers on Sunday and holidays? What’s up?

...In November 2013, Amazon.com announced it was working with the U.S. Postal Service to deliver packages on Sunday and holidays, starting in Los Angeles and New York, and in May, it added 15 more cities. In recent weeks, it has rolled out to even more cities, including Seattle, Portland, Northern New Jersey; San Diego; Fort Worth, Dallas and Houston in Texas; Richmond, Va.; Washington, D.C. (plus Virginia suburbs).
