Even after people have RTFM, many are still misunderstanding the pricing model. For instance, people now think you can store 2TB of data and download 100GB of it at once (5%) for free. Nope! You can request a max of 0.16% per day of data for free. Once you exceed 0.16% of your data in any given day, you start getting charged. I think it's fair to say that even with the intent to RTFM, the pricing model is unusually strange and AWS should really put more effort into explaining it.
