Kaplan eBooks for iPhone / iPad downloads for free
Until August 30, the Apple iBookstore offers downloads of almost 100 Kaplan eBooks for iPhone / iPod touch / iPad for free. (In order to view this offer, you need to access the iBookstore via the iBooks app on your device.) That's the best deal we've seen for this collection of study guides."
