got a call from bookadda. here is what i was told... the book i ordered was out of stock. but they got one copy for me on priority basis. the book they got was an expensive edition. it is also a revised edition of the book. it is priced slightly higher at around Rs. 190. but i am not supposed to pay this price. i would pay the original price. book would be issued from their center today. should reach me by tomorrow or day after. the guy who called me up was probably a senior guy. did not sound like a customer care chap. i am getting a feeling again that this is twitter effect in process.
