If we talk about selling used gadgets, there are very few companies who serve at your doorstep. I came across one company cashify. They purchase your used phone in few quick steps. Talking about my personal experience neither did I only get a better price of my old used phone than others, but what I would like to appreciate most about the company is that they came to my place to pick up the phone and I got my cash then and their, which I found quite appreciating. I would personal recommend cashify to get off your old used gadgets and that too from your place.
