One of the reasons why I love amazon is that they are cheaper than netflix. netflix is 7.99/m for their online streaming service. This comes out to be ~$96/year.
Though Amazon on the other hand is 80/year for their Prime membership. This comes with a lot more than just their streaming service. You also get their 2 day free shipping and their kindle library which allows you to rend a ebook once a month.
Amazon is doing an amazing job of changing of how people consume products and their entertainment. While all at the same time the customer by providing it to them for cheap.
