Harry Potter Book 7 has a release date

Yay! The final Harry Potter book is definitely coming this year, July 21, to be exact. Bill and I are unabashed fans of the books (the movies less so). But check out the weird: Amazon is selling the hardcover for $18.89 (list price $34.99) and something called the "deluxe edition" for $39.00 (list price a ridiculous $65). I can't figure out what's so deluxe about it. Whatever it is, I can't see how it's worth that much more.
