Amazon's home page provides three methods to start finding and buying items. The front page itself shows off featured items, and once the site starts learning your tastes, it will display products based on your history. To find a specific item, type in the search bar at the top of the page. Press "Enter" to search the entire catalog, or select from the drop-down menu set automatically to "All" to search a specific category, which also enables the "Refine" capability for more specific results. If you'd rather just window shop, click "Shop by Department," to pick a section to browse.
Some other large e-commerce sellers use Amazon to sell their products in addition to selling them through their own websites. The sales are processed through Amazon.com and end up at individual sellers for processing and order fulfillment and Amazon leases space for these retailers. Small sellers of used and new goods go to Amazon Marketplace to offer goods at a fixed price.[148] Amazon also employs the use of drop shippers or meta sellers. These are members or entities that advertise goods on Amazon who order these goods direct from other competing websites but usually from other Amazon members. These meta sellers may have millions of products listed, have large transaction numbers and are grouped alongside other less prolific members giving them credibility as just someone who has been in business for a long time. Markup is anywhere from 50% to 100% and sometimes more, these sellers maintain that items are in stock when the opposite is true. As Amazon increases their dominance in the marketplace these drop shippers have become more and more commonplace in recent years.[citation needed]

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 addition to pulling in hosting revenue from companies like Disney, Netflix, and Spotify, AWS is also the backbone of the company’s own internal infrastructure and the underlying foundation for its Alexa digital voice assistant. It is a major competitor to Microsoft and its Azure platform, as well as Google’s cloud computing division and the cloud businesses of IBM and Oracle. AWS is so important to the integrity of the apps and websites we use that a rare S3 outage, which is the web hosting pillar of AWS, took out large swaths of the internet.
Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians,[178] and former employees,[179][180] as well as the media and politicians. In 2011, it was publicized that at the Breinigsville, Pennsylvania warehouse, workers had to carry out work in 100 °F (38 °C) heat, resulting in employees becoming extremely uncomfortable and suffering from dehydration and collapse. Loading-bay doors were not opened to allow in fresh air, due to the company's concerns over theft.[181] Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees.[181] The company eventually installed air conditioning at the warehouse.[182]
