documents: #Person1#: I'd like to buy a bottle of Centrum, a dozen tooth brushes, some baby's wipes, and a small bottle of aspirin.
  #Person2#: Centrum? We have bottles of thirty and one hundred tablets. Which kind do you want?
  #Person1#: Give me one bottle of one hundred tablets.
  #Person2#: And what kind of toothbrushes would you like?
  #Person1#: Can I have a look at them?
  #Person2#: Sure. This brand is supposed to be very good, but they're expensive. Those are new products. They come in several colors and sizes. There is also hard, soft, and medium.
  #Person1#: Are they cheaper?
  #Person2#: This one is 10 % off. That one has no reduction, but you can get a free tube of toothpaste with six toothbrushes.
  #Person1#: So if I buy a dozen, I'll get two free tubes of toothpaste?
  #Person2#: That's right.
  #Person1#: Good. I ' ll take a dozen of them then.
  #Person2#: And here is your aspirin. What else did you say you want?
  #Person1#: Baby's wipes. Johnson's.
  #Person2#: Anything else?
  #Person1#: Well, actually I'd like to buy some vitamins for my son. He's five months old. Can you suggest any?
  #Person2#: Sure. Here you are. This one is excellent. Just mix one drop of it with milk.
  #Person1#: Thanks. That'll be all.
