Check the fine print though with things like magazine subscriptions, book clubs, contests, and the like.
Funny story. I have been receiving DVDs and movie posters for a few years from British Columbia, Canada and could not figure out where they were coming from and thought maybe I had a secret admirer. Nope. I have been entering predict the movie weekend box office take on The-Numbers.com for a few years and I guess they do not alert you have won. I guess I won a lot more than the two times I was actually aware of from checking The-Numbers.com news.
