Exchange

Sale it on olx

Last when I checked, Samsung had tie up with Cashify for exchange of old phones. They're responsible for such low quotes. It's better to sell them at a vendor or on Olx or Quikr, they'll offer a reasonable price. Also, one thing is true abt electronics is that once u open the box, the resale value becomes 50% and gradually keeps going down. Only Apple phones offer u good resale price but again the price mathematics is the same. Their cost is higher and so is their resale value. No one can do anything abt it(at leastin India). You can sell it in your circle if the phone is in good condition.
