Radio Shack says it will give you at least $30 for your old clunker. To get the $300, you need to trade in the 64GB Apple iPhone 5 (AT&T) or the Samsung GALAXY Note II in like-new condition. Don't forget all of the cables and chargers that originally came with your trade. Adding those to the trade will increase the value.
If your phone has no trade in value, Radio Shack will be happy to recycle it for you. But just keep in mind that one man's garbage is another man's fortune. Just because the LG Voyager has zero trade value at Radio Shack doesn't mean that a collector wouldn't pay something for the device. It might be a good idea to check eBay before you give an older handset away for nothing. And by the way, the Voyager is going for as low as $10 to as high as $50 on the online auction site.
