For those who care ICv2 released their top 50 rankings for comics sell through to consumers:

Of course there are not definitive and this is a relatively small sample size for stores and what they are selling but it does provide some general idea of the state of things. Unfortunately, but not unexpectedly, no Superman comics appear in their rankings except for Justice League. Considering they only had SSoKE at #34 last month and the expected drop for second issues it is not too surprising to see it fall off the tracking entirely but still worth noting.
