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. 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. 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. 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.

I do not like the security of this apps. By default any one in my home can just open it up and start buying things on my account. I would like it to just add things to my cart on the TV and them buy on "My" Computer or "My" phone. I know you can setup a PIN for "videos, purchasing and certain types of content".But, you then need to enter the PIN for $0 videos. Also, anybody with access to the Fire TV remote can just install the apps and start buying things, no pin, no password, just because you have a Fire TV setup on your account. Amazon you need to have a separate PIN for Buying videos, parental control (ratings), Apps and Shopping. And by default the app should setup a PIN.
