HVAC Drafting And Design

Worst book. I have purchased this book. And I had opened the cover after 20 days of delivery. So I don't have chance to return. But this book is totally waste. It has only 61 pages. And this book has only definitions , no in depth details. And there is no printed rate in this book. I want to ask Amazon, why customer has to pay 4700 RS for a book which has only 61 pages and how customer can make sure that , book rate is correct or not without printed rate.
