This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I am not sure about Delhi, but you definitely can buy the book at Amazon The prices at Amazon are about one third of the price in New Zealand. This is because you avoid the middle man. Even including shipping costs it save me at least 50% of the costs. If you order a book at Amazon USA there is a big chance the book will actually be shipped from Germany as this is closer to India.
