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.
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.
At first I thought, why do I need amazon on my tv? But then, I thought, of course I need amazon on my tv! It’s actually pretty handy, and I’m not talking about just ordering shows or movies. If you just want to look at something quickly, there’s no need to fire up the computer or tablet or look for your phone (which I can never find quickly). If you want to show someone a product, poof, it’s on the tv which is so much easier to look at than my tiny phone screen! Also, if you use your alexa voice control, it’s all hand free. Admittedly, mine often has to be told a couple of times and the transition isn’t seemless by any means, but in all, it works out pretty well when I remember it’s available!
