Haven't seen this posted yet. Carnival is doing a contest for the next month where you can win some items from the Destiny, and also a trip on the new Sunshine. Just click the link and then click the red 'get started' button on bottom. If it asks you for twitter and you don't have one, just close that box out and you can still earn points from watching videos and such. They are also doing weekly drawings for Destiny prizes so just by signing up you are entered for that too.
Good Luck Everyone!
