But one of the biggest differences between Cyber Monday and Black Friday remains: the style of shopping, says Vice President of PR and Events at Slickdeals, Regina Conway. “For example, we see more sitewide discounts or category-wide discounts on Cyber Monday, whereas Black Friday will often have very specific products such as electronics and home goods at deep, deep discounts,” she says. “However, more merchants have started advertising specific product deals on Cyber Monday and vice versa, so the holidays are starting to have more crossover.”
In 2013, Amazon secured a US$600 million contract with the CIA, which poses a potential conflict of interest involving the Bezos-owned The Washington Post and his newspaper's coverage of the CIA.[200] Kate Martin, director of the Center for National Security Studies, said, "It's a serious potential conflict of interest for a major newspaper like The Washington Post to have a contractual relationship with the government and the most secret part of the government."[201] This was later followed by a US$10 billion contract with the Department of Defence.[155]
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:
If your new dress doesn't fit right or a gadget arrives broken, Amazon accepts returns on most sales within 30 days of delivery. In general, third-party sellers offer the same policy, although you'll usually have to pay for return shipping to the seller unless the seller advertises free returns, whereas Amazon often provides a prepaid shipping label for its own returns. The cost of the return may be subtracted from the refund if the item was returned for some other reason than Amazon's mistake.
Goodreads is a "social cataloging" website founded in December 2006 and launched in January 2007 by Otis Chandler, a software engineer, and entrepreneur, and Elizabeth Chandler. The website allows individuals to freely search Goodreads' extensive user-populated database of books, annotations, and reviews. Users can sign up and register books to generate library catalogs and reading lists. They can also create their own groups of book suggestions and discussions. In December 2007, the site had over 650,000 members and over 10 million books had been added. Amazon bought the company in March 2013.[100]

Many U.S. states in the 21st century have passed online shopping sales tax laws designed to compel Amazon.com and other e-commerce retailers to collect state and local sales taxes from its customers. Amazon.com originally collected sales tax only from five states as of 2011, but as of April 2017, Amazon collects sales taxes from customers in all 45 states that have a state sales tax and in Washington, D.C.[166]
