Don't buy the book at Amazon.de - They have raised the price again to 97 Euros! Absolutely nuts!
Buy the book at Blurb.com - link below

Blurb is located around the world so you can order the book from a Blurb-site nearer to your country and closer to your home address (SELECT the flag of the country you are in or select WORLD). It only takes Blurb less than 5 business days to produce the book and a couple of days to send it to you. Ordering directly at Blurb.com you pay around 35 Euro + shipping.
I do NOT recommend buying it at Amazon.de at this point in time. Both Amazon.co.uk and Amazon.com has the correct price.
All the best
