I "won" one of these last week and then yesterday got an email saying that I hadn't given them all of my information and so had to enter my address again. I know I did enter my mailing address originally, so either their site is messed up or they are trying to get out of some of these by making people re-enter their address. It certainly wasn't a big deal to do so, but I almost deleted the email as I'm sure a lot of people will do.
