From USA Today:
With 200 million people in the USA using cellphones, countless thousands of phones are lost or damaged every day. Savvy entrepreneurs are finding ready customers online seeking alternatives to contracts and full-price phones.
Type “used cellphone” into a search engine, and scores of possibilities pop up. CraytonElectronics.com, Cellphoneshop.net and usedcellphones.com offer online stores of used phones with guarantees and warranties.
While used phones are cheap, the downside is that you’re buying someone else’s castoff, says Peter Rojas, editor of the tech enthusiast website Engadget.
