Posting for general interest of FMs in Delhi and NCR region. Mr Vijay Kumar runs a shop at No. 634, Old Lajpat Rai Market, Chandni Chowk, Opp. Red Fort in Old Delhi Area. He has a large and wide collection of both brand new and used Audio Cassettes. His collection includes all Hindi movie cassettes, Ghazals and Devotional. The starting price is usually Rs. 25 per cassette. But the final price depends on his moods and the number of cassettes you end up selecting/ buying. All cassettes are kept in cartons. So one must have a lot of time and patience to look around and find the hidden gems. You can reach him on his mobile number. His landline are temporarily out of order. Best wishes !!
