Don't give up so easily :-)

You can buy it from the publisher directly since they do international shipping. Contact them for the shipping charges.

You might also want to check Amazon India and see how much it costs to order from them.

Talk to some of your local schools/colleges/libraries and see whether they can get it and you borrow from them.

Finally; ask your "Indian Friend" (direct/indirect) to get the volumes on one of his/her visits to India ;-)
