What can I do for you?
I want to buy a sweater for my son. This yellow one doesn't have a price on it. How much does it cost? Do you know?
Yes, it's $ 42.33.
That's too expensive.
Here's a nice nylon one for $ 15.88. We sell a lot of these.
Yes, it is nice. I think I'll take it.
Do you want anything else? This kind of trousers is in discount. It only costs $ 13 each pair.
That's nice. OK, I'll take one.
