Now another new quick service from Google, all time when we search a book on Google, we have to go to that store who is selling that book. But now google make the life easy by giving option to buy the book on spot without visiting Book store.  Its as easy as 1,2,3 just search, select and buy.

Already, Google makes it possible to download or print over one million public domain books in a partnership with Sony. Those books are all available in the open ePub format. It would make sense if Google Editions were also available in ePub, but the plan to turn regular browsers into eReaders probably needs something else like Google Gears.

And also if u want to buy from other stores then google give you a comparison of all store prices. yeah its soo simple.
