My local store never ever stocks Ms. Marvel, Agents of Atlas, Moon Girl or Squirrel Girl because the owner hates them and thinks they are ruining comics. I have a pull box and he still doesn't order them. I have to drive to Huntsville to get stuff like Unstoppable Wasp, which was probably the best comic of last year. There are a lot of unsold X-men and Spider-man issues sitting on his shelves.
That is absolutely not true everywhere. My local store sucks ass. But it is definitely not rare.
