ecoATM offers a safe, fast, and easy way to sell or responsibly recycle your old cell phones, MP3 players, and tablets. Get up to $400 instant cash for selling an iphone or up to $150 for a Galaxy.  Visit their website to find a kiosk location and get an estimate of the price of your device. Once you insert your device in the kiosk, it will be assessed based on model, condition, and current market value. You will then receive a quote for the highest price ecoATM can find in a network of buyers, and you can decline or accept the offer for instant cash.
