Yes, I agree with @Cilivren, it seems to be more likely that you'll win a smaller prize sweepstakes or contest, mainly because there tends to be less interest in those prizes. The small prizes are almost all I've won, except for the La_z_Boy recliner. I enter both the large and small prize sweepstakes, with the hope that I'll win some small ones and all I need is one large one .
I'm not into this kind of gambling, and I don't usually enjoy any of them. To Lose my time with Contests or sweepstakes for meager prizes is not very encouraging. I respect people that enjoy them though. Doesn't cut for me. Many businesses do a lot of contests as a marketing strategy, but I find them, in most cases, obnoxious.
