Ahhh the famous Roto-Rooter "Blue Juice"....
Did you know there was a minimum sales quota of "Blue Juice" the Roto-Rooter Tech is required to sell each week?
Last I knew a friend of mine who worked at the company said it was $45.95 a gallon... I'll bet it's well over $50 by now...
If you feel compelled to buy miracle drain cures may I suggest Bio-Clean.
At least then you won't be paying the bloated mark up of a large corporation.
