I have purchased the PDF version of some books, including ADWR, and at the time I did not want to purchase a paper version.
Now going back to the page, there isnt a way to purchase the paper books, it is only possible to re-purchase the PDF+paper, or PDF only.
Think you guys could add an option for people that pre-ordered only the PDF versions to pay the difference and pre-order the paper books too?
That would be really neat, and I would be very happy.
Thank you, and by the way, great job on the books, they are very nicely written, fun and rich.
