听力原文：W: Have you decided what you're doing for your summer vacation, Mark？
M: Well, Liz and I would like to go to Italy together, but the prices that our travel agent has given us are way out of our budget. It's probably because it's the busy season.
W: Well' have you thought about trying one of those last-minute deals？ If you don't care about flying first-class, sometimes flights are cheaper when you book late. You might want to try a search on the Internet. There are also discounts with some companies if you order online.
M: Thanks, I'll give that a try. I hope it works out. I don't want to be stuck at home!
