I am so surprised about what I have learnt that I need to share with you. It seems to me that you are selling a FREE book.
I have just visited the web site of the publisher (http://greenteapress.com/wp/think-pyt...) to get the source code of the exercices and I have seen that the pdf of this second edition is available for FREE DOWNLOAD.
This FREE pdf is exactly the same as the one you sell except the covers....
Could you confirm that you are selling a document which obeys the Creative Commons Attribution-NonCommercial 3.0 Unported License.
If yes I want a pay-back.
