My secret supplier of free lined drums is from a candy factory. I have noticed most places do not return messages. Coca-cola.....bakery.........machine shop............
I would seriously call as a drum recycleing impersonator. Just to find out what they do with their drums.
Most of the time they get a shipment once a month all at once. Use product and crush for scrap. At least around here. I ended up with 24 drums per month for free if i needed that many. I took 7. Clamps lids all included.
