answer: #Person1# wants some discount to promote sales, but #Person2# doesn't agree with that because it's the lowest quoted price.
documents: #Person1#: I wonder if you could allow us any discount for this commodity. It's the general practice that wholesalers usually get some discount from manufacturers or suppliers.
  #Person2#: As a rule, we don't allow any discount.
  #Person1#: But we usually get a discount of 3 % to 5 % from our other suppliers. Actually, some discount on your prices would make it easier for us to promote sales, you know.
  #Person2#: That's true. But I am sorry I can't make an exception. We have quoted you our lowest price. We can't give you any more discounts.
