Those are the emails that say "fulfillment" right? I have 4 sitting in my "waiting for prize" queue. The most recent is 12/9, so I'd say I'm winning still.
I think a slow economy and pre-Christmas times both increase the number of people entering contests. I have found in the past that starting around 12/20 and continuing through most of the winter that I have more wins than I do in the fall. Although this is my first recession doing contests, so I guess that may make a difference through most of 2009.
The biggest difference I see this year (and starting about halfway through 2007) is that I win way fewer DVDs. Maybe it's just a random thing, or maybe more folks enter than they used to for DVDs. I even started, in the last 2 months, entering for the daily entry DVDs and I'm hoping that will improve my odds.
Good luck!
