Spoke too soon... another 3 books using 65% codes...
0.35 * $6.59 = $2.31
3 * $2.31 = $6.93 => €5.05 total price.
That's €1.68 a book. The paperbacks would cost me €7.95 a piece.
I love ereaders and the Kobo store.
This way, I'll someday complete my Forgotten Realms collection (~325 books) at a fraction of the price I'd normally pay for it in paperback. (I've just started buying them starting from the first one, so the entire collection is on my wishlist

Pity there are quite a lot of the older ones that Kobo does not have.)
Oh, and adore Alf and calibre. Because of those, I don't have to worry that I'll only read some of the books two or three years from now, even if my device changes. Best is that they don't take up any space. If I was still reading paper books, I would never have had buying sprees like this because of cost and space.
