She can’t sell unless she’s a #1. Then Marvel has likely done statistical analysis that’s demonstrates diminishing returns and end of profits after 4 issues of certain characters like Silk.

It makes sense though we see so many limited series and short story arcs. The world went and got itself some serious attention deficit disorder. Most people likley can’t be bothered with long running stories, etc. So it suits most people’s attention spans I think…
I orderd a total of 7 of the Sandman Frison 1:100 covers from 3 places combined pre-FOC, Sanctum shipped despite resale skyrocketing. One ebay order for 4 at $400 total had a “LOL I cant ship the ones you ordered as I am out” when I followed up for my order. Just my experience.
