Heard a commercial on the radio today.

It began with a guy trying to sell his used toothbrush held together with duct tape. It made the point that there are some things you don't want to buy used.

Sure. Let me think, in addition to toothbrushes, there are definitely things I don't want to buy used like say mattresses, underwear, diapers, condoms, plenty of things.

So what was this commercial pitching? What is it that I definitely don't want to buy used?

A home.

Apparently buying a home where someone else had previously lived and used, possibly a number of other people can be equated to buying a used toothbrush.

If that's not conspicuous consumerism, what is?
