I get junk in the post, most of my post is junk. I have a sticker on my letter box from the council saying "no junk mail, yes please to council publications and local newspapers" I still get fliers and junk several times per day.
I think it would be easier to pick out the three bits of proper mail that are delivered in a week from the recycling rather than the current arrangement of shovelling handfuls of fliers off the door mat.
I've lost it haven't I?!
