Don't want to destroy the joy for this edition, but it does seem kind of a rip off that first they sell a highly overpriced limited edition of the book, don't answer if it will be available as a normal paperback book - and then finally release it for 19 bucks on amazon.
Anyway, I will be getting this, it's available on German Amazon prime for 18,82€ (probably 19,99$ in €).
