Clean copper dropped from $3.25/lb to $2.50/lb at my local scrap yard. Add 18% to $2.50 and mine should go up to about $3.00/lb. ($2.95). Thankfully we're moving soon, and I can give the demolition crew a little less dumpster chow.
OT: How much is aluminum going for in your area? My yard gives 55¢/lb, up from 35¢ last Winter.
