Whats interesting about my yard is for aluminum they buy it all as "old sheet" which I dont know if thats dirty or clean or a mix but I just throw all my aluminum clean, or with a bit of plastic or stuff on it and they pay $.45 / lb for it without cleaning it... Could just be for me because there nice but who knows, I keep it fairly clean anyway. But my prices are around the same $.03 - $.05 for shred. Taking a load in tmrow morning and ill know more, stockpiling shred still.
