UPDATE (June 18, 2009): The discount on the book is gone just one day after the launch. The price is back to $99.00. The Simulator and Flashcards still carry the discount.
UPDATE (June 29, 2009): The Simulator and Flashcards are mysteriously "unavailable" now. Earlier, they were available for pre-order but not at this time. We gotta wait :(
UPDATE (July 02, 2009): Thankfully, the discount on the book is back. It's now available for $77. Much better than paying $99 + $10 S&H at RMCProject.
