It's easy!
    Each dealer starts with 100 points.
    If the wife does the packing, add 10 points.
    If wife has day job, Add 10 points
    If she works for the IRS, subtract 20 points.
    If the bill arrives before the shells, subtract 10 points.
    If extra shell arrives with package, add 10 points.
    If data comes from the Philippines, subtract ten points.
    If data on dealer's form, add 10 points---even if it's wrong. At
least it will  be  legible.
    Now you get the idea. And you can add items to the list that
interest you.
    (I also invoke indulgence 512 Blue for boring you.)
