It's great to see Roger Stern posting on CBR
I'd also like to mention Marvel Digital has expanded to the point where they do collections and not just single issues now. I don't recall seeing this option earlier this month in any case.
For $10, I got Doctor Strange: The Oath. They recently updated the viewer too and it is much better. I will have to check into the Dark Dimensions by Stern and see if they are offering that one too.
