Scrap sellers/papermarts/raddiwalas that keep book

Hey folks looking for any scrap sellers, papermarts or raddiwalas that still keep books(novels, fiction, nonfiction etc) I want to buy books cheap and these are the best options I feel. I am looking for any raddiwalas you might know that still keep books. Please be as specific as possible with the location details. It could be anywhere from CSMT to Kalyan and Churchgate to Borivali. Note- try not to include any bookshops/bookstores.
