documents: #Person1#: Mr. Smith. could you give me your quotation for your bicycle A5, FOB Qingdao?
  #Person2#: Can You tell me how many you want to buy?
  #Person1#: 100 for immediate delivery, and 500 in two months time. that's by the end of July
  #Person2#: Well. then, 260 yuan each.
  #Person1#: Since this is a sizeable order, I was thinking you might give us a 5 % discount.
  #Person2#: I'm afraid we can't go as high as that. You know we usually don't give any discount. but considering the newly established business relationship between us, I could give you 3 % off the list price.
  #Person1#: Only 3 %? That's not much. If you could make some concessions, we would probably buy some of your other products.
  #Person2#: OK. OK. I don't want to haggle with you. Let's say, how about 3. 5 %?
  #Person1#: I think I can accept that.
