Gazelle.com is a website where you can buy used cell phones, or sell your old phones. Has anyone tried them? How do they determine the condition of a used phone that they receive? I also considered selling my used phone on eBay, which I think may be more of a hassle, but I may get better offers. My phone that I want to sell is an iPhone 5c. It's not an expensive model, relatively, but it's in great condition. I never took the case off. I'm leaning towards using gazelle because it seems very easy.
