Long story short - Stardock sent me a coupon valid to January 28, 2014, which is suitable for any Stardock PC game or DLC, excluding GalCiv3.
Joke is that I own everything they have to offer (minus War of Magic), and even gifted my friends games they wanted. So I simply don't have anything to spend it on, and decide to give it away. If you planning to buy something from Stardock in those few remaining days, post here and I'll give code to you.
If moderators consider this post inappropriate, well, my apologies.
