Sharing my personal experience and looking forward to explore more options! Thanks!
The all new Cashify App (https://play.google.com/cashify) is quite amazing. Caught my attention during the recent buzz about their exchange programmes. I had a Samsung Galaxy Grand Duos which is more than two years old and I was looking for a right platform to sell it for the best price. I tried downloading the app which is only available for Android OS as of now and might be available for iOS soon I guess. Frankly speaking, I was quite amazed with what it does. Introduced by ReGlobe - a firm that buys old and used gadgets through their buyer network, Cashify is an all star that offers convenient, secure, fast & easy way of selling old gadgets. You get a price quote within a fraction of seconds once Cashify finishes to diagnose the mobile automatically. It's your mobile's personal doctor and tops the charts of my favourites' list. I got INR 4200 for my phone which was higher than what the other portals were offering! Also a free pick up of phone in addition. It's a must try! I am sure everyone will enjoy the steps that are included in the self-diagnosis process! Views are my own! Thanks!
