How so?
Digital numbers aren't published.
One time, it was said that most titles sell about 10% digitally from their paper sales.
And that Ms. Marvel was the exception. We were told it sold more than it's physical sales.
Mind you, that was more than a year ago. A lot can change in a year.
I'm not saying Ms. Marvel doesn't sell digitally, but to say that it sells 25k-30k isn't based on anything.
