Cashify has tied up with OLX for mobile sale, so if you try to sell Mobile phone on OLX you will be first given the option to go to cashify site and people who are not net savy will visit cahify. After you give basic detail you get an x amount, and as more details are given this amount goes down to .7 x and when their representative visits and wastes your time then it offers .4 x . So I was told Rs.5000/ for my phone and after giving details where nothing was missing the value was 3750/ and after seeing the mobile they offered 2250/
