I feel like this guy was up late and on edge and just wanted to rant about something, some pretty obvious things were missed in his analysis of Amazons practices. For instance he appears to have totally missed the fact that the $9 bottle actually was two 32oz bottles, so it was 64oz for $9. His distrust just cost him a ton of money.
Considering the author also admits to accidentally subscribing to things in the last. I would say they have a reading and paying attention to detail problem. :x
