Why don't magazine photo spreads show the prices of all items?

Question

Often in magazines, the photo fashion spread will list the items, the designer, and the prices. But sometimes the prices aren't shown. Why is that?

Answer 1

I think it could be the same reason that items in boutiques have no price tag: If you have to ask... you can't afford it.

Another possibility is that the price varies depending on where you buy it.
