From the announcement:
We decided to skip Gen Con this year, to focus on getting our new kits out. The great news is that we are having a web sale to share our regular, fantastic convention specials with everyone. Starting the morning of Thursday the 14th and going until the evening of Sunday the 17th, all kits will be discounted 25%. In addition, if you buy any 6 assorted kits, you will receive a FREE copy of War & Conquest by Rob Broom (a $45 value)!
