Sure, we all know about Black Friday, but Cyber Monday is currently upon us. Games Workshop has jumped on the sales wagon and is offering the digital version of their codices for 40k and Battlepacks for Age of Sigmar for special prices.
If you've been meaning to pick up a codex or two to see what your opponents are up to, you can get them for £10 off the regular price. And going digital makes it easier to move all those books around. The sale won't last very long, though. So go now.
