As posted in a thread by Spud
"Tilkeys drum recyclers - 80 ltr drums are from memory about $13.00, they cotained citric acid or that acid they put in softdrink. They are UN specified containers so they are good quality. They also have 135 ltr drums for about $15.00."
prices may vary, call and ask ?
