Amazon allows users to submit reviews to the web page of each product. Reviewers must rate the product on a rating scale from one to five stars. Amazon provides a badging option for reviewers which indicate the real name of the reviewer (based on confirmation of a credit card account) or which indicate that the reviewer is one of the top reviewers by popularity. Customers may comment or vote on the reviews, indicating whether they found a review helpful to them. If a review is given enough "helpful" hits, it appears on the front page of the product. In 2010, Amazon was reported as being the largest single source of Internet consumer reviews.
Amazon's state sales tax collection policy has changed over the years since it did not collect any sales taxes in its early years. In the U.S., state and local sales taxes are levied by state and local governments, not at the federal level. In most countries where Amazon operates, a sales tax or value added tax is uniform throughout the country, and Amazon is obliged to collect it from all customers. Proponents of forcing Amazon.com to collect sales tax—at least in states where it maintains a physical presence—argue the corporation wields an anti-competitive advantage over storefront businesses forced to collect sales tax.

Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians, and former employees, 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. Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees. The company eventually installed air conditioning at the warehouse.
