Couldn't find a "not new" thermostat

My thermostat broke. I did LOOK for a thermostat at Buffalo ReStore (they often have new merchandise donated from stores and manufacturers), but had no luck. Didn't have time to look further: I needed heat! I did resist the fancy-schmancy Nest and Lyric thermostats that you can program from your phone (over $250 AND I don't trust them). I did spend the extra $6 ($26 total) to get a 5/2 day programmable unit even though, being retired, we don't need it. I figured the next owners will appreciate it.
Turns out thermostats often contain mercury and need to be properly recycled. You can find out where here: http://www.thermostat-recycle.org/zipsearch
