Just when you thought you were done with sending J.K. Rowling all of your money... In the final book of the Harry Potter series, Harry Potter and the Deathly Hallows, Harry finds clues in the book of fairy tales wizards read to their children. And now you can get a copy of Tales of Beedle the Bard for yourself. I mean, for your kids. Obviously.

Only one of the stories in Beedle is referenced in Deathly Hallows. That's "The Tale of the Three Brothers," and it's joined by "The Fountain of Fair Fortune," "The Warlock's Hairy Heart," "The Wizard and the Hopping Pot" and "Rabbitty Babbitty and Her Cackling Stump."

Advance sales are strong, as you'd expect. There's a $12.99 hardcover edition coming out this week, massively discounted at just about every retail outlet. And Amazon is publishing 100,000 copies of a $100 collector's edition.

The most collectible edition would be one of the seven illustrated, hand-written copies of Beedle Rowling had made last year. Six went to close friends, and one was sold at auction (to Amazon, for a magical $4 million) to benefit The Children's High Level Group, a charity she helped found in 2005.

Net proceeds of Beedle will help institutionalized children in European countries including Romania, the Czech Republic, Georgia, Moldova and Armenia.
