I keep cans. I get about $13-$14 per bag of uncrushed cans (big black bags) and I usually cash them in when I have 3-4 bags. I tried glass and plastic, but it was too much work and you don't get much for it. My city put a machine in place years ago that separates the trash from the recyclables, so I just put the glass and plastic in the trash. The city decided that too many cities that had recycling programs were not making money because people would come around in the night and still the recyclables in the bins waiting to be picked up in the morning. So they decided to invest in the "The Machine". I have no idea what it is called or what it cost.
