received call telling  me I had won a big prize from an entry I submitted at a mall

Someone call me up and told me I have won a coupon for some Plasma TV

I just received a phone call from a Sam Albert who stated that I had filled out a ballot and won one of 5 prizes (cash, laptop, furniture) at Walmart...first of all I NEVER fill out ballots.  Sam stated that I would have to sit through a presentation and would be served light refreshments.  WhenI told him that my husband was unavailable he insisted that he need to be present...why?  if I had won the prize.  This sounds like a marketing scheme that I want no part of.
