Add it to your Wishlist on Amazon and watch it for a while. I'm pretty sure an American will resell one. I got mine used on Amazon.in after stumbling on a fine day that someone was selling it for ₹399 (~$5). So, bought it. They shipped it all the way from the USA and it took more than a month.
Checking it right now shows ₹1,388 (~$17) for the Paperback and ₹2,261 (~$28) for the Hardcover edition.
wow, the book is only physical and it costs $60 to get it where I live... (without import taxes)
