Buying books has one of the best methods for comparison shopping:  the ISBN.  To search for a specific title, go to Amazon where the ISBN is listed (you can pick either the 10 or 13 digit number).  After highlighting it, you can paste it into Google and then go to Google Shopping where you can see all the different prices.  Don't like Google Shopping?  Take it to another deal site like PriceGrabber.
