“Puerto Rico was devastated by Hurricane Maria a few short weeks ago, and is in dire need of humanitarian assistance and relief. We’ve organized this bundle to provide what help we can. The proceeds for this bundle will be going entirely to GlobalGiving’s Puerto Rico and Caribbean Hurricane Relief Fund.”
Also, if you purchase this bundle, editor Chris Stevens will give you a free download link for his Truly Terrifying Vampires supplement. No proof of purchase is needed – just let him know you bought it and what email you use for DriveThruRPG.
