I just checked. Postage (in Euros):
Great Britain: 9,31
I wish it was cheaper to ship shit. So, if you decide you don't want the book, I will totally understand. It's quite a bit of cash for a 'free' book.
By the way, if you would like to get more than one copy, the good news is that it won't cost you any extra postage. For Patrons any extra book will cost €7,50 (€5,50 cost + €2,- for my illustrator and me.)
