HBO has a giveaway running right now (open to US and UK residents only) that is pretty cool. You can enter for a chance to win crowns featured on Game of Thrones! The grand prize winner takes home Robert Baratheon’s crown, as seen in season one, while the 1st place winner gets Joffrey’s crown, as seen in seasons one and two.
Just submit your email at the contest page to be entered. You can enter once per day, until the contest ends on May 7th. The contest is open to US residents only, however there is a similar contest running for UK residents. Good luck!
