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