RadioShack has had a limited trade-in program for a while now, but they have just announced that it will become available at all 4,400 of their stores. Take your working used electronics in, show an ID and you will receive a gift card for your efforts. You can also go to their site and get an appraisal and free shipping label. The items are limited to MP3 players, cell phones, gaming consoles, peripherals, computers and a few others, so check with them to find out if your used device qualifies.
