Say again how much?

Regarding the previous post, I think the book is sort of sold out, and another edition is at the moment not in sight. Just because Thom contacted me to check out the price, I did a quick search on google, and the book is going from 75 to 400 dollar, wauw, that made it for me the best investment in years because I bought it for 50 euro. So forget about shares by books...:)
