thanks for your swift response and explanations! :)

yes, I thought so that a question of "price" was more like of other value than direct monetary one.

however for me it was related to the things I've tried to analyse previously, regarding "Consumers", "Product" and "Advertisement". thus your discussion of this other side - has provided additional "facet" to this matter. :)

so, that's why nowadays many such things, including "Price" are more like kind of idiomatic, rather than literal... that's what I was trying to say.
