This book store over charges and has faulty books so check clearly if all the sections are there. If you're trying to sell second hand books, then they do not give as much money as the books are worth.
The worst book shop. They sell books at high prices. And the shopkeepers are highly impolite and rude. They act tooo arbitrarily. I will sue them. Nevere ever go to such a shop and there are many other good book shops in delhi and in this row also.
