If cheap is what you are after, just: Step1= Buy a gallon jug of apple cider/juice from the grocery store. One of the jugs with thicker plastic. Step 2= drink the juice/cider until it is gone Step 3= fill with hot water and start using as your jug The residue from the apple juice actually smells good. The jugs last me generally 1-2 years until I need a new one. For mild west coast climate, this is my go to solution.
