Mumbai - Demonetisation has taken aback everyone, exchanging and withdrawal of the money has become a big problem. Medical shop owners are taking Rs 500 and Rs 1,000 notes but they too need cash to return. Too much of their time spends in getting cash from the banks and ATMs. Selling and buying of medicines is getting hampered because of the shortage of changes. Maharashtra Registered Pharmacist Association has written a letter to state finance minister Sudhir Mungantiwar asking solution for the problem. In the letter they have written, " Wholesalers should take Rs 500 and Rs 1,000 notes or else make new notes available for us at earliest."
