Hi all.  We are looking for a new supplier for copper sulfate for our foot baths.  Currently been purchasing from our local IBA route guy, but for plenty of reasons, looking for a new supplier.  Currently, Fleet Farm is charging $80/50 pound bag, and Stockmans wants $90.   I looked  online, and Animart is about $60, but there is a hazardous surcharge, $30/shipment, plus freight.  

Im in Wisconsin.....Where does everyone get a good buy at?   

Thanks
