Something You Don't See Every Day

I just got back from my almost-daily trip to Krogers, and tonight while checking out, I noticed something that I hadn't seen before.  It was a machine the size of an ATM that gave you cash for your old cell phone.  I didn't look at the fine print, so I don't know if they only give you cash for iPhones or new phones or what, but I was definitely intrigued.  I wonder how much they'd give me for my ancient Nokia flip phone?
