(S1 hands Bs a product catalogue, and after a while they begin) ’d like to get the ball rolling by talking about the price. What prices will you offer for these I ticked?
S1: Before anything else, can you give me any idea what kind of order will you place?
A larger one, then handsome discount, as a matter of course.
B2: That depends, for Item One, we’d like to purchase 1500 units, and for Item 3, 1200 units perhaps more, so quote us your most competitive prices, sir?
S2: The usual price we offer for these two items are the lowest we could provide, For Item 1, it’s 3 yuan FOB, (地点) for Item 3, 2 yuan FOB(地点).
B2: That seems to be a little high, Mr. Hu, I don't know how we can make a profit with those numbers., you know, the competition is tough, and the costs are rising fast.
S2: Well, if you promise future business, with large quantities, why not, we can come down a little, that way, we may establish a long-standing cooperation between us.
B3: You know, the market has shrinked a lot during the economic recession period, it’s even hard for us to make ends meet. Furthermore, our customers are asking for the best possible.
S3: We understand it, but you know it’s good value, and they are newly cultivated after we invested a lot into the R&D. I believe you know the cost we spent.
B3: Yes, we know that. It’s because of that, I hope we can cooperate to open the market. If the price is reasonable, good sale
