Ever wonder what to do with a landline telephone or a cordless phone when it no longer works? There really isn't a market for donating them to charity, reselling them or listing them online to give away; if the phone doesn't work, nobody can benefit from it. But the phone and its components are recyclable. Best Buy accepts any type of landline phone for recycling. Just bring it to the store, and they'll accept it for free, regardless of if you bought it there.
