I was contacted by the President of Cliffhanger Productions. He explained Catalyst's decision not to include the code with the PDFs. According to him, it is to promote purchases at local game stores. I have to say, I am 100% behind this decision now. I probably still won't buy a Print Copy (this isn't because I can't find one it's because I literally do not want another physical book in my collection), but I have to say that what they are doing to try and boost local store sales is a good thing.
