Hi if anyone has the promos that were exclusive to GenCon I am willing to pay quite a bit for them. I have been looking for a while and have not been able to find them. email me if you have them and we can hopefully work out a deal. My email is awipi3@yahoo.com. Thank you
Nothing is exclusive to one con or another. Also, you can print your own copies of the promos off of bgg.
If you really want the actual copies, though, then I guess this works.
From what I've heard they're planning on releasing all of the promos as a pack after they're done expanding the game if you're willing to wait.
