I emailed him asking about the availability of the Fallen One (before I decided to order one from Germany instead), but received no reply.
That's odd. I emailed him last Saturday afternoon about the order from April(*) and got a reply within about 5 minutes. The email was just to the shop@ address, so nothing special.
(*) It turns out he'd forgotten about my order, so put it in the post (it arrived yesterday). He also upgraded it to a diorama version, by way of apology, which was very decent of him.
He's having a Summer sale at the moment
