Hm... really nobody buying, or is the reporting delayed? According to Amazon, I have sold a grand four copies so far - two on .com and two on .co.uk - and Lulu says I've sold nothing.
I didn't exactly expect a bestseller, but four is a bit frustrating.
I'll be buying a copy in the next few hours, soon as I figure out which option is going to hurt me least in currency exchange fees.
