Amazon Germany lists the German translation of the latest Jo Nesbø novel for pre-order at these prices:
Hardback: €22.99, $30.40, £19.54
Kindle: €19.99, $26.43, £16.99
I.e. the Kindle book is only 17% cheaper than the print book.
BTW, there's no RRP for books in Germany, because of the
Buchpreisbindung (
Fixed Book Price Agreement).
