The American Red Cross and HBO are teaming up to mark the final season of “Game of Thrones” with a “Bleed for the Throne” event.
The event challenges fans to donate blood and in return they are entered for a chance to win one of five trips to the season 8 world premiere of “Game of Thrones.”
While supplies last from March 7-12th, blood donors can get a Game of Thrones T-shirt and sticker with a unique Snapchat filter to the event.
The sweepstakes promotion runs until March 17th at participating American Red Cross locations. For more information, visit their website.
