What price do you suggest for 300,000 sets of Article No . 2323 with London as the destination port ?   Let me see . It's £ 800 per set CIF London .   What commission terms can you offer ?   Usually the commission is three percent of the net invoice amount after deduction of discounts .   Couldn't you raise the commission to five percent ?   Considering our good relationship and our future business , we give you four percent . That's the best we can do . We can't go any further . What would you say to it ?   Then I'll accept it with thanks .
