A: I've come about your offer for bristles. B: We have the offer ready for you. Let me see... Here it is. 100 cases of Tsingtao Bristles, 57mm, at... pounds sterling per kilogram, CIF European Main Ports, for shipment in June, 2009. The offer is valid for three days.

B: But you must take the quality into consideration. Everyone in the trade knows that China's bristles are of superior quality to those from other countries.

To be frank with you, if it were not for the long-standing relationship between us, we would hardly be willing to make you a firm offer at this price. A: Well, we'll have a lot of difficulties in persuading our clients to buy at this price. But I'll have to try, I suppose.
