The Amazon sales rank (ASR) provides an indication of the popularity of a product sold on any Amazon locale. It is a relative indicator of popularity that is updated hourly. Effectively, it is a "best sellers list" for the millions of products stocked by Amazon.[134] While the ASR has no direct effect on the sales of a product, it is used by Amazon to determine which products to include in its bestsellers lists.[134] Products that appear in these lists enjoy additional exposure on the Amazon website and this may lead to an increase in sales. In particular, products that experience large jumps (up or down) in their sales ranks may be included within Amazon's lists of "movers and shakers"; such a listing provides additional exposure that might lead to an increase in sales.[135] For competitive reasons, Amazon does not release actual sales figures to the public. However, Amazon has now begun to release point of sale data via the Nielsen BookScan service to verified authors.[136] While the ASR has been the source of much speculation by publishers, manufacturers, and marketers, Amazon itself does not release the details of its sales rank calculation algorithm. Some companies have analyzed Amazon sales data to generate sales estimates based on the ASR,[137] though Amazon states:

In November 2013, Amazon.com announced a partnership with the United States Postal Service to begin delivering orders on Sundays. The service, included in Amazon's standard shipping rates, initiated in metropolitan areas of Los Angeles and New York due to the high-volume and inability to deliver timely, with plans to expand into Dallas, Houston, New Orleans and Phoenix by 2014.[79]

According to an August 8, 2018 story in Bloomberg Businessweek, Amazon has about a 5 percent share of U.S. retail spending (excluding cars and car parts and visits to restaurants and bars), and a 43.5 share of American online spending in 2018. The forecast is for Amazon to own 49 percent of the total American online spending in 2018, with two-thirds of Amazon's revenue coming from the U.S.[51]

The company has also invested in a number of growing firms, both in the United States and Internationally.[67][68] In 2014, Amazon purchased top level domain .buy in auction for over $4 million.[69][70] The company has invested in brands that offer a wide range of services and products, including Engine Yard, a Ruby-on-Rails platform as a service company,[71] and Living Social, a local deal site.[72]
