I suspect there is an economy of scale in that if the same piece of junk mail is delivered to 100 house it only really needs to be scanned once unless it has some kind of unique code as it wouldn't matter whose piece of junk mail you got a picture of. Otherwise I'm with you in thinking this is absurdly cheap.

I don't think they can count on that. There are often subtle mail-merge changes in junk mail contents between recipients. Something as simple as "Dear Frank" or "Dear Mr. Jones" makes this unfeasible.
