From: penny x stamm <pennyx1@Juno.com> | . | Byron & Margaret, I would never have a call for 3 lb coffee cans, but I | do have a collection of empty gallon Clorox ( or non-name brand) | bottles which Jim has saved for collecting used oil.... You might try checking with a hospital, nursing home or school kitchen to get the gallon size cans they get vegetables in. They get rusty but last for years if you have a place to store them.
