Can I buy a key? My interest would be in finding out how you would react if I told you I intended not to use the software (other than to test the key in a throwaway VM), but to publish the key in this thread, and then fill out a report at microsoft.com/piracy with a link back to this thread. Given that, how much for an Office 2013 key and what bitcoin address should I pay? 
I would then tell you the following: You have done incriminated yourself as much as I have, and will be just as guilty. So, for future reference this post shall be screen captured
But, feel free to send .15 to 1EwCHGXiTYotCAirxB7Ehxzc4ASTt6MyMM. You will receive a link to your ISO and your activation key on the 3rd confirmation.
