The rate at which they keep adding 'tempters' to this release (Cherub, print, lowered shipping cost, now Moffat signature) I get an uneasy feeling that they are having definite issues shifting as many of these as they would have liked, or perhaps expected. I really hope they don't end up losing money on this, as I want them to do well, and I definitely want more Doctor releases in future.
That said, I wouldn't be terribly surprised if these aren't selling very well. It really does seem like one of those ideas that seems good on paper (wouldn't it be cool if we did actual 'stone' Angels in scale?), but the actual practicality of it, given that the retail price point required to achieve such a thing with the unique tool and materials needed for this release, probably should have put the kibosh on it before it ever saw sculpt. I mean, let's face it, this truly is a niche within a niche, and even amongst the hardcore Doctor Who collector fanbase, few people are likely to pay the high price that a release like this demands. Or at least in my view, anyhow.
On one hand I applaud them for trying something different and thinking outside the box, I just hope they haven't bet the farm on the profitability of it, that's all.
As for Moffat's signature, no interest whatsoever.
