Earlier quoted context omitted.
I recommend buying your computer books in India. US Price for this book is $150 USD. India price is around Rs. 427 which is around $7 USD. Textbook prices, like everything related to education and healthcare are excessively high in the US. A reasonable price would be around $50, which is what this book would cost if it wasn't a textbook. The same book in Amazon India: http://www.amazon.in/Operating-Systems-Implementa…
I was eager to take your advice. Problem is it can't be shipped to the US.
Another suggestion is Barnes & Noble. (Yes, really.)
I myself had borrowed a copy through interlibrary loan back in November after checking Amazon for A couple of weeks ago, I had to kill some time, so I meandered into a Barnes & Noble for the first time in years and on a whim tried to look up Operating Systems: Design and Implementation on bn.com. Turns out, bn.com operates not just to sell B&N wares, but also apparently as a sort of hub for third-party sellers, (just?) like Amazon. I was surprised to see the market rate for used copies was $34.50, so I snagged one.
Meanwhile, the AbeBooks link above has a shrink-wrapped copy for $16.52.
Takeaway: don't assume that Amazon is the end-all-be-all, even for books.
