November sales weren't posted here, so:

TMNT Ongoing #76 12,258
TMNT Ghostbusters II all sold between the 10,000-12,000 range
TMNT Universe 16 8,044
No December sales yet of course.
Universe only sold 8,000 copies this month, might be the lowest a IDW TMNT comic ever sold unless I'm forgetting something.
