We recently did a mass clean out of our attic and garage. I found a box with all our OLD flip and slide cell phones from the past 15 years or so. Not smart phones... seriously old time flip phones. It's quite sad - looks like a casket or time capsule full of old timey cell phones. Not sure why we kept them at the time, but I want to get rid of them responsibly... not just trash dumping. Any suggestions for websites or places to recycle, donate, etc? They are all too old for Gazelle.com, etc... need other options. Much appreciated folks.
