If you were hoping to have your Sheldon books by Christmas, here's your last chance: you have until Saturday to order your books for Christmas delivery. We'll still be accepting orders and shipping after that, of course, but Saturday is your last big chance to get one under the tree.

Lots of folks have been praising the new book, especially. In e-mails, forum posts, in the press and in famous encounters.

So please don't wait until Dec. 24th and wish you had snagged a copy...as that will just bum us both out. Snag yours now.

NOTE: Make sure you order using Priority Mail, as Media Mail won't make it in time.
