I have to say that I have been spoiled over the last couple of years by ICv2, the site I use every month for my market watch. They do such a great job of breaking down the sales of comics by units sold, ranking titles.
And here are the sales for Supergirl #65, the first issue of the Kelly Sue DeConnick/ChrisCross three part arc, the last story for this Supergirl pre-DCnU.
So without an issue count, it is hard to fully grasp these sales figures. Supergirl #64, the last Peaty/Chang issue ranked as the 82nd ranked comic in May. Here in June was see that Supergirl #65 is now the 116th best selling title. Was there a freefall in sales? Was there a 'this story doesn't matter' ennui that led to people dumping the title?
Or is this more a matter of there being more comics out there. Every Flashpoint crossover outsold Supergirl. There were a lot of Fear Itself minis above her too. Did people buy these new titles instead of Supergirl? Or as well as Supergirl? A number would be helpful.
Anyways, I hate to see Supergirl ranked so low regardless of a flood of 'event comics'. It also makes me happy that DC remains confident in the character enough to continue some version of Supergirl in the DCnU.
But it would be a shame if prior fans are missing out on this fun story by DeConnick and Cross. If you have left, come back!
