M: I'd like to buy a bottle of Centrum, a dozen toothbrushes, some baby’s wipes and a small bottle of aspirin.

W: Centrum? We have bottles of 30 and 100 tablets, what kind do you want?

M: Give me one bottle of 100 tablets.

W: And what kind of toothbrushes would you like?

M: Can I have a look at that?

W: Sure. This brand supposed to be very good, but they are expensive. Those are new products. They come in several colors and sizes. There is also hard, soft and medium.

M: Are they cheaper?

W: This one is 10% off. That one has no reduction but you can get a free tube of toothpaste with six toothbrushes.

M: So if I buy a dozen, I'll get two free tubes of toothpaste?

W: That's right.

M: Good, I'll take a dozen of them then.

W: And here is your aspirin. What else did you say you want?

M: Baby’s wipes, Johnson's.

W: Anything else?

M: Well, actually I'd like to buy some Vitamins for my son. He is five months old. Can you suggest any?

W: Sure, here you are. This one is excellent. Just mix one drop of it with milk.

M: Thanks, that'll be all.
