If it were to get support, CV could be used to scan for matches, and folks who are scrapping stuff that they know is not just late capitalist disposable trash they can offer it up.
People could make their own deals based on the actual value of the thing. I figure if someone were to send me pull handles that match my dresser, I'd buy them a very fancy coffee, at least, besides shipping and handling and time.
But I like the idea of it being a community thing we do, not a site you go to.
