Are you going to buy a bicycle?
I'm thinking about it. How much is it?
¥ 350.
Oh, dear. It's too expensive. Can you give me a better price?
Your discount is already included. Normally we charge ¥ 400, but now we can give you a special price. This is our sale period.
It's still too much. Can't you make it any cheaper than that?
Sorry, but this is the best price. You can't get it any cheaper than here.
I see. Can I pay by traveler's checks?
I'm afraid you can't. You're welcome to pay in cash.
