Time for some scary treats! Click the banner above to go to DriveThruRPG and hunt around for the Jack-0-Lanterns. Click on the Jack-0-Lanterns for some free swag.
To get you started, I'll point you to two:
Kobold Quarterly Issue #15 - Go to the "FAQ PAGE" and click the Jack-0-Lantern. It will appear in your cart for $0
All Flesh Must Be Eaten - Revised - Click the Jack-0-Lantern at the bottom of the "HOME PAGE". Enjoy ;)
There are thirteen freebies in total. I know I haven't found them all. Feel free to post the others you find in the comments below, and I'll add more as I find 'em.
(don't switch between the various OBS sites without checking out with your free purchase, or else the free purchase may end up in the second cart at regular price)
