because of some unforeseen events, i will have 60 additional copies for sale next week.

so i have opened the paypal links on the order page again:

so... fire away if you still need a copy.

and for the people who are still waiting for their books: it seems like surface copies to the US take about 6 weeks. If yours went out with the first batch on Nov 26 (all pre-ordered copies) you should receive it any day now; any orders after that will take about 2 weeks more.
