We got this CompUSA catalog at work. What's weird, is that every item in the catalog has an 'add to cart' button. What the hell?

Funniness ensues:

Tech: Hello, thanks for calling CompUSA.
Me: Hi, I'm having a problem with the catalog?
Tech: Yeah, sure. What can I do for you?
Me: Okay, well. I have the catalog open to the page I want, and I see this item and this thing that says 'add to cart.' So I opened the website so I could check that it goes into my cart and I've been pressing the button, but it's not doing anything.
Tech: You just... click it.
Me: Well I don't quite understand, it seems to be printed on paper.
Tech: I don't... okay, what are you trying to do?
Me: I want to buy this item, and I'm pressing the button to add to cart...
Tech: Where's the button?
Me: In the printed catalog. Why doesn't it work?
Tech: Because it's a catalog. They don't do that.
Me: Then why is it in there?
Tech: So you can add to... I don't know. Do you want a sales person?
Me: Sure.

Then we hung up.

Oh, days at my real office.
