Until a few weeks ago here is what I did. If the book was missing matches I shucked them. I kept full books. I had a few bulky binders and decided to shuck them all as I decided it is the covers you are saving them for, not the matches. If they are feature matches you leave them. I now am down to half the binders I had. As far as mailing them there is a round robin floating around now with over 300 matchbooks in it. Barry
