I'm not sure why the disparity--I don't have anything to do with setting the prices. Perhaps B&N charges more of a seller fee than Amazon? Not sure. Either way, it's a pretty good deal for a book that has had consistently good ratings! So if you've been waiting to grab your e-copy, now is the time.
