I'm not sure what's worse - running a contest that no one enters, or in my case, laying out about $14 bucks on a prize with S&H, and the contest winner by mistake copies me in on an email he sent to a friend basically saying he won a piece of crap and wants to get rid of it. I also asked the winner to email me when he got the prize (which he never bothered to do), but at least his mistaken email let me know it was received.
IMO, I would rather have the contest that no one enters, and at least I keep my piece of crap.....
