Well, some stores.
According to reliable sources on the East Coast, the book has showed up in comic book stores there. No word yet on whether or not it is in bookstores on the East Coast or not, but we do know that it has not made it to the West Coast yet.

EDIT: The book WILL be available everywhere — it’s just early in the East, is all.
