W: [ 12 ] Hey! You got a new television.
M: Yeah! It was delivered yesterday. What do you think of it?
W: It's huge. It practically takes up the entire side of the room.
M: I know, I know. You don't think it's...well.., excessive, do you?
W: I didn't say that. I mean, if you enjoy it, why not? What happened to your old TV, anyhow?
M: [ 13 ] It just stopped working last Friday. It was pretty old and didn't work well. I thought: I can afford it, why not get a new one?
W: It must've been very expensive..
M: Well, not as much as you might think. I got it on sale for 50% off.W: Really? Where?
M: At the Household Appliances City on Route 7. You know at first I just wanted to replace what I had--a TV of about the same size and quality. But the salesman was pushing these because of the 50% off.
W: Yeah. But 50% off what?M: 2,400 dollars.
W: You spent $1,200 on a TV?
M: It's got a lot of special features. Look at this remote control.
W: I'm sure. [14] But that's still a lot of money for a television. I didn't think you watch TV that much.
M: Well, I don't. Do you think I ought to return it? If I do it within a week of purchase, I can get my money back.W: Honestly, yes. And you know what, [ 15 ] I think you ought to read up on relative websites first and choose the model you want before you go to the store. That way you will get what you want.
M: I think you are right.
