What do they need to order?

Woman: What do we need to order?
Man: Well，we’ve got enough paper—we don’t need any more.
Woman: That’s right，but we need half a dozen new calculators.
Man: No, we don’t. Have you forgotten? We ordered eight calculators last week and they should arrive bythe end of this week.
Woman: I’d completely forgotten. You’re right.
Man: Actually we need some more pens. There’s only a few left.
Woman: Right. I’ll order some more at once.
