Yep, $800.
That's what I saw, too...which makes me curious why everyone thinks that was such a smoking deal, anyway. As soon as OP listed the book (before the take its and drama started), I glanced at GPA just for the heck of it, and saw a 2013 GPA sale for that book @ $450, and a 2012 sale on a 7.5 for $158. I thought...dang, he's pricing that pretty aggressively...he probably thought so too, until he (I guess) got a better offer
As a side point of curiosity...something happen in the last 3 years that would double the price of that book?
That does seem odd and I have no idea what that book is worth.
