I've dug around more and actually something strange is clearly going on with the whole site, very few of their recent books are in stock and when you dig enough to find older stuff by other authors that you can actually add to your cart THOSE things are free too. So it's a bug and I'm guessing the reason the figures are shipping separate/at all is because they are dispatched from a different warehouse that hasn't caught wind of the problem.
You think they would have just shut down the whole store while they figure it out given it's been like this for at least 10 days, I find it very hard to believe no one's noticed. The publishers' Twitter has still been updated regularly since /co/ noticed the issue so it's not as if the company collapsed or their social media team disappeared off the face of the earth.
Curious, very curious, I'll say that much. Anyway, everyone who hasn't should definitely order a figure at the very least since they're confirmed to be shipping, you have nothing to lose and I doubt they'll make more comic-based merch like that ever again, it's bound to be a pretty rare thing
