What will the price be if they buy 30? How will Mr Wang dispatch the order?

M: They are exactly what we need. The only problem is the price.
W: How much do they cost?
M: $60.
W: If we buy 30, what discount will they give us?
M: 10%.
W: What if we bought 100?
M: We’d get a higher discount, but we’d never be able to sell them all.

M: Purchasing.
W: Mr Wang here. About your order—how would you like it sent?
M: Well, road is probably cheapest, isn’t it?
W: Yes, but it’ll take 10 days, is there a rail depot near you?
M: No. There isn’t. I suppose you’d better put it on the plane, then… it’s urgent.
W: OK. We’ll deliver in 48 hours. Does that Suit you?
M: Yes, that’s OK.
