They pay the same $9 rate for what you saw, they do that for appliances and junk and cars, you can get better rates for better sorted stuff but it's not worth my time.
699.5123 lbs., approximately.
I spent today pulling about 300 screws out of an old truck body we had ripped apart with my bud's backhoe so it could go as clean aluminum at $.57 a lb instead of dirty at $.18...Got $250 instead of $80 so I figure it was worth it. If you have the right tools (Sawzall and bolt cutters do great at separating) and a little time, it might pay...Or not. Aluminum is so light it take a bunch to get any weight. An entire box truck body netted me only 440 lbs. of aluminum...
