Q: M: But, Jane, why not rent one with Handbag Hire? Instead of $ 990,pay $ 50,and you have it for a whole week. W: Sounds great, but I never knew I can rent a handbag. M: Handbag Hire is a new business. It was founded two months ago. Its collection covers many designer handbags. W: So... for the price of one Murrberry, I can use a different bag each week for twenty weeks? M: Absolutely. And if you like one of them, you can choose to buy it at a discounted rate. Of course the price varies by age and condition. For example, a $ 1500 Murrberry bag can sell for just $750. W: Great, but how do I rent? By telephone? Or in person? M: Either. And more conveniently, it accepts online orders. W: I'll do it on line now. I still have one more question. Mary's wedding is next Saturday. There are only five days left. Do I have enough time? M: Don't worry. It promises that customers receive their orders by post within two days. Three more days to go. W: Oh, I'd better order one right now. What was said before this conversation?
