Just thought I would share my deal huntn' skills with everybody.
If your not familar with Microsofts cash back program, its pretty easy, Just log into a site via there search engine, pay for something with paypal and after so much time pases you get the money back as a %
It was made big by ebay as they had 30% cash back on ebay for awhile... ebay deals are gone but once in awhile you find other good deals. In this case I noticed Barnes & Noble currently have 10% cash back.
So log onto this page:

Go buy your book, sit tight in like 2 months (yes it takes a long time but you get it back when you dont expect it like a bonus) you get your money back.
