[speaker001:] Good morning. What can I do for you?
[speaker002:] Christmas Day is coming. I want to buy several postcards to send to my family and friends. Can you recommend me some?
[speaker001:] Of course. How about these postcards? They are specially designed for Christmas.
[speaker002:] These postcards are great. I want to buy a dozen with different pictures.
[speaker001:] No problem. You can choose what you like.
[speaker002:] How much is a postcard?
[speaker001:] A postcard costs you five yuan. A dozen postcards cost you 60 yuan.
[speaker002:] OK. Here is the money. Thank you very much.
[speaker001:] You are welcome.
