I work for them. Prices change and sometimes daily or a couple times a day. They have just recently changed again as of today 1/30/20. so you can not go by what they were it is a daily thing you need to find out.
As of 01/24/2020: Tin = $130/gross ton Bare Bright Copper = $2.33/lb. Clean Aluminum = $0.23/lb
