Do you have a drawer full of old cell phones? You've got the latest fancy-schmancy instrument, and you know there's no way you're ever going back. What are you going to do with all those old ones?
SecondRotation might buy your tired old phone from you. Enter your brand and model information and see if they're interested, and get an estimate of your item's value. The actual price you get will be subject to their inspection after you send your phone in. If you're trying to get rid of something left over from the '90's, they may suggest recycling rather than making an offer to buy it from you, but if you have a perfectly reasonable late model phone that you're not using because you just upgraded to the latest iPhone or some such, you just might get their attention.
In addition to phones, they're also interested in other electronics, like laptops, digital cameras, camcorders, and more. Hey, instead of just the kitchen drawer, this may be your chance to clean out that closet full of electronics as well.
