I'm running a huge sale on a bunch of my 28mm-scale cardstock model kits. Choose from dozens of terrain sets for under $1 each. They're designed to be easy to assemble with just a few common hobby tools, and many of my PDF kits include a variety of graphics layers you can adjust with a click of your mouse, so you can customize your models before you print. It's a great bargain and a ton of fun. The sale is on now at Wargame Vault, RPGNow and DriveThruRPG.
