Today is the last day we are guaranteeing delivery-before-Christmas to those who preorder the LessWrong books to North America (i.e. US, Canada, Mexico).
Order them at lesswrong.com/books by 12pm midnight Pacific time to still be included.
Thank you so much to everyone who has purchased the 1,600 copies already sold. We've increased our print run by an order of magnitude to account for the demand curve.
I'm looking forward to hearing about people opening them for Christmas :)
