The short answer is no. I'm not going to do that - however you can buy Postcard Cthulhu, Postcard Empire, and Postcard Dungeons and get them sent to you right now by going to www.postcardgames.com
The long answer is I've calculated everything based on the most that can be put into an envelope and have it still count as a piece of standard mail. Adding anything would throw that off and I'd have to charge more for shipping, which would defeat the purpose. Also once fulfillment comes around, it's best if I can send everyone exactly the same thing (as much as possible).
