Not that you should need an excuse to donate blood in the first place. 

But this is a pretty cool perk that you can win just by doing a decent civic duty.

The Red Cross has partnered up with HBO to offer the once in a lifetime grand prize of a trip to the world premiere of the final season of GOT.

Anyone who donates blood by March 17th will automatically be entered in the drawing.

To schedule an appointment you can call 1-800-733-2767 or visit redcrossblood.org.
