Tampons

A woman walks into a drug store to buy tampons. She notices a group of tampons stacked on a table in corner with a sign on them saying, "5 boxes for a dollar" The woman just could not believe this price so she asked the clerk if it was correct. He said, "Yes, five for a dollar." She said, "That can't be right!" Clerk says, "Yes, it's correct. See here? Five boxes for a dollar, no strings attached."
