Griffons Forge has new website hosting, so the problems they’d been having with online orders should be a thing of the past.
From the update:
Griffonsforge has switched hosting services. The move corrects some of the problems our customers were having in ordering and is more mobile friendly. The majority of our catalog is now available at our new site including our Alien Hive Terrain and Sci-Fi Terrain, as well as a few of our DwarvenForge add-ons.
