So we don't have November numbers yet but in the top 50 sellers list Inhuman #8 was placed at 29. Looking at October sales this puts #8 around 55K. Then again, as I understand it Marvel sent out twice as many copies to comic stores as were originally ordered. So without the push by Marvel the series might have shipped around 27-28K which is a slight drop from October.
Really hope Marvel will let the comic continue.
