They usually never come on Saturday or Sunday unless you chose a specific deliver day option
Amazon doesn't deliver, they just sell.
For usps, ups, fedex, dhl... no Sunday service unless someone paid for it. VERY expensive. For all except USPS , Saturday service is also very unlikely.
Regarding Amazon delivery by the Post Office on Sundays, the list of cities included for this service must include your address.
If you are an Amazon customer residing in the Greater Los Angeles area or New York metropolitan areas, you do not need Amazon Prime service to have an ordered item delivered on Sunday. In this Los Angeles Times news story, the United States Postal Service (USPS) has entered into an agreement with Amazon and began delivery of Amazon packages on Sundays to customers in the Greater Los Angeles area or New York metropolitan areas at no extra charge in November 2013.

Nope. Not Sunday & not usually even Saturday, unless you pay extra.
