Amazon has a virtual monopoly on digital Marvel comics, but it's just opened up another way to get them. Kindle owners can now purchase single issues through Amazon's store without needing the Comixology app as before. You can still get Marvel comics through Comixology, but of course Amazon acquired it last year, so the money goes to Jeff Bezos either way. All told, you'll be able to purchase up to 12,000 back issues of titles like Guardians of the Galaxy, Daredevil and The Amazing Spiderman at the Kindle Store. Moreover, all titles will be available the same day they arrive in regular stores.
