This contest has been going on for a while but LEGO has a contest for a chance to win an exclusive platinum LEGO Star Wars R2-D2 minifigure. All you have to do is fill out their form and you’re entered. There will be two grand prize winners of the platinum R2-D2 which is worth about $3,300.

I tried it when it was first started but it was having issues with my entry but it looks to be working now. The contest will run until January 1, 2018 at 12:01am EST.
