The blue one is much cheaper, but it doesn't look as good as the black one. A: Oh! I can't decide. What time is it? B: It's only 6 o'clock. We've got plenty of time. A: Really! I thought it was later than that.B: Why don't we go to another shop? A: No, I've decided. I like the black dress better. It's the most expensive, but it doesn't matter. B: OK. Let's go and pay for it.
