If you don't win the book it is worth buying. I bought mine from Amazon, there was a small issue that meant they had to replace my copy. All taken care of without any fuss. Great people to deal with.
Did you know you were in it?
I would have linked up Amazon but they seem to be out of stock. I'll stick the link here anyway, in case it comes back in >>> http://amzn.to/2ylPzjT
