Easy! Just choose the book-only reward (by hand or by mail), and multiply the pledge for the number of copies you want. For instance, a 76 euro pledge means two hand-delivered copies of the book. Shipping is only paid once, so if you want three books delivered in Europe you should pledge (38 * 3) + 7 euro, meaning 121 euro total. At the end of the campaign you will be able to choose the language of every copy separately.
