eBay is the best site to find out University books and other science books (becaise i am science student).
My most intrested areas of searching are chemical engineering and environmental engineering books
-RC-1 to 6 (Chemical Engineering)
-Chemical Reaction Engineering
Above all of this i am also intrested in to searching and purchasing the Notebook (Laptop) and fernitures.
Last but not lease i would like to say thank you very much to generator of the eBay and team of the eBay, because they make easy shopping and easy life.
