This number showed up in my call display.  It was an autodialler playing a message to the effect that "a friend or family member" had entered my name into a sweepstakes and that I had won a week's free vacation at some wonderful resort somewhere, all expenses paid, blah, blah, blah.  The message stated that several major retailers were behind this contest, including Sears, The Bay and a few others I don't recall.

A few weeks ago, I had the exact same call from a different number.  Obviously, I rejected that offer as well.
