Ads on toilet paper rolls

  Anyways the toilet paper roll is going to be used and thrown into the bin. How about asking corporates to put their advertisements on it? The corporates could then sell the toilet paper roll for less than a penny (subsidize the price).
  That way, companies catch the attention of the people 'REAL Time' !!! (Truly Focussed Advertisement) and people won't mind using the buying cheper toilet paper rolls!
  It's a win-win situation for both the buyer and the seller!
