Motion 30-Day Trial CD

Yesterday, I received my first ever mailing from Apple: A Motion Demo CD including a link (http://www.apple.com/go/motion) that redirects to a page where I can activate a 30 day trial license to Motion or where any interested parties can register for the same trial and be sent a link to download the demo. The page notes: "If you already have a Motion Trial CD, just fill out this form. Your code will be sent to the valid email address you provided within the next hour." The demo is save disabled, the canvas area and exported movies are watermarked, Final Cut Pro HD and DVD Studio Pro integration is disabled, and only one of the several templates included with the retail version of the software is available with the demo.

Now this 30-day Motion demo isn't anything new. It's been around for a while, and Apple has
pointed to it in various places. What I am wondering is why they bothered sending me a CD of it? I've never checked any boxes saying "Please feel free to mail me stuff," and, since I already own the full registered version of Motion, I do not know why I would be targeted with this promotion.  Anyone else out there receive one of these? On the plus side, the cover packaging for the CD
is one of those angle-animated pictures where you shift the angle slightly back and forth to see movement of the picture.  Hours of fun!
