To give you price references, in France: 1. _Nim in Action_ is currently at 39.99$ (3 275,80 Indian Rupees at current stock market change). I got it at a discount price at Amazon for half the price two years ago, 19.99$ (1637,49 Indian Rupees). 2. I got _Mastering Nim_ for 61.81€ (about 5551,54 Rupees). This book is quite expensive since all the pages are colored for the syntax highlighted code.
> Both books are quite expensive in India. Mastering Nim is not available in > Amazon India. This is a confusing sentence. If _Mastering Nim_ is not available, you can not tell whether it is expensive. You can read this online book for free: <https://ssalewski.de/nimprogramming.html>
