What’s the main topic of the conversation?

W: 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: It just stopped working last Friday. It was pretty old and didn’t work well. I thought you can afford it, why not get a new one?
W: It must have been expensive.
M: Well, not as much as you might think. I got it on sale for 50% off.
W: Really? Where?
M: At the stereo city on Route 20. 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 this because of the 50% off.
W: Yeah, but 50% of what.
M: 2,400 dollars.
W: You spent 1, 200 dollars on a TV?
M: It’s got a lot of special features. Look at this remote control.
W: I’m sure, but that’s still a lot of money for a television. I don’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? I think you should read up on TVs first, choose the make and model you want before you go to the store. That way you’ll get what you want.
M: I think you’re right.
