What I do



Cut ends off cords to get #2 ins price. ($.93 lb.)
If the ends are brass twist them off and put in brass bucket ($1.66 lb.)
Put cut cord end in Copper content bucket ($.14 lb. here)
If the end has gold connectors cut them off and put them in gold connector bucket. ($.65 lb. add to a shipped load of ewaste)
All other ends get cut and pit in Copper Content bucket as well
Ends that have transformers get removed and plastic smashed off to get electric motor price (.20 lb.)
