Searching for an image processing book in any city


I'm located in Peshawar and am in desperate need of the book "Digital image processing using MATLAB by Gonzalez" I have searched all of the engineering book stores in peshawar and they tell me that the book is short.

So can I please ask my brothers in other major cities to see if the book is available in their city.

And if anyone already has that book and wants to sell it they need not look anywhere else for a buyer.

Thank you

update: I found the book on this website: does anyone have any experience with buying books from there?
