documents: #Person1#: We're considering of ordering 200 computers, but I'm wondering about the price you'll possibly offer.
  #Person2#: Our price will be not less than $ 5000.
  #Person1#: Your price is higher than I expected. Could you give us a little discount?
  #Person2#: This is already our best price.
  #Person1#: But the price is always negotiable and you should consider our quantity of order.
  #Person2#: Well, what would you suggest?
  #Person1#: Could you make it $ 4500?

  #Person2#: You drive a hard bargain! OK, that's a deal.
