If you’ve been wanting to catch up on some back issues, but don’t have the scratch to blind buy from your comic shop’s quarter bins, then I have good news for you: DC Comics is now available on ComiXology Unlimited.  For a small monthly fee, you’ll have access to tons of DC Comics content, along with even more books from other publishers.  That means you can read Batman: The Dark Knight Returns, Batman: The Long Halloween, and Scott Snyder and Greg Cappulo’s New-52 run for the price of a new single issue. Head over to Comics Now for more details.
