documents: #Person1#: Excuse me, I want to know the price of your CPU.
  #Person2#: Glad to tell you. The price of CPU is 300 dollars.
  #Person1#: It's rather too high. If you can make it cheaper, we will be able to place large orders continuously.
  #Person2#: If you order a large amount, we can give you a discount.
  #Person1#: Well, can you explain it to me?
  #Person2#: The price of CPU is 260 dollars above 1, 000 Units.
  #Person1#: Can you reduce more?
  #Person2#: I'm sorry, but to be frank, considering exploiting the market in your country, we have already supplied you at very low preferential price.
  #Person1#: In that case, we have to stop ordering if a reduction can't be made. Please reconsider.
  #Person2#: It is so hard to deal with.
  #Person1#: If you can give us a more reduction, We'd be able to give you an order on the spot.
  #Person2#: This price is the best we can make.
