Digital comic book retailer Comixology is offering a FREE digital copy of The Walking Dead #19, which features the debut of Michonne, one of the series’ most popular characters.

The sword-wielding badass from The Walking Dead was revealed in the last minutes of the television show’s season two finale last Sunday, and while many comic book readers were celebrating, others were left scratching their heads at the site of a woman in a tattered hooded jacket, holding a sword and leading two zombies on chains. Granted, the debut of the character was an awesome sight, but fans who haven’t read the comics have no idea of the significance of the character. Enter Comixology. Comixology and Skybound are not run by stupid people. Offering the debut of the character for free is a perfect way to bring in fans of the show to check what fans of the comic have known for years. Michonne is totally awesome.

Comixology announced on Monday that, in conjunction with Skybound Entertainment, the online comics retailer will be offering a free digital download for The Walking Dead: Days Gone By to WonderCon attendees.

You’re going to be hard pressed these days to find many people attending a comic book convention that haven’t yet read the first collected edition of The Walking Dead by Robert Kirkman and Tony Moore, but if you are one of the poor souls who haven’t experienced the first chapter of this zombie apocalypse epic that spawned a mega-popular television show, or if you just want the the digital volumes, then this should definitely be on your radar. At this weekend’s WonderCon in Anaheim, CA, free downloads of the first volume of The Walking Dead will be available for the first 5,000 people that visit the Comixology booth (Booth #107).

Vertigo Comics announced Wednesday that they’d be kicking off their brand new digital comics app with a 99 cent sale on all Sandman comics.

So, there’s two things going on here: DC Comics has split their Vertigo Comics imprint from the main DC Comics app to give all of the Vertigo titles a digital home. That’s right! New comics like Fairest, Saucer County, Domique Laveau: Voodoo Child and The New Deadwardians will all be going day and date digital, while established books like The Invisibles, American Vampire, The Unwritten, Fables and many, many more will also be making their way to the Vertigo-only app. Which is pretty cool.

Digital comic distributor ComiXology is now running a 99 cent sale on IDW’s Doctor Who comic books. The sale, entitled the “Time Warp/Leap Year” sale, is running now through 11pm EST on Thursday, March 1. Unless you have a TARDIS, here is your chance to grab at this awesome deal.

The leading IDW Doctor Who series follows the current Matt Smith incarnation of the Time Lord on adventures with companions Amy Pond and Rory Williams, set during the events of Series 5 and 6. IDW also has a Doctor Who Classics publication, which reprints the timeless comic strips that were once published in Doctor Who Magazine.

Icon, the creator-owned subsidiary of publisher Marvel Comics, has possibly one of the best stables of creators and comic book titles in their arsenal, and care of Comixology, you can catch up on titles like Criminal, Powers, Casanova, and more with a cool 20 percent off sale.

Yes, that’s right! You’ve seen the praise for Ed Brubaker and Sean Phillips‘ creator-owned work on this site before, and that’s with good reason, as Criminal and Incognito are two of the most innovative works in their fields. Both comics completely suck you in to their gritty, crime-ridden world setting and tell a story that is simply unforgettable. I even suggested that you catch up on Criminal on this past week’s GoD List, so if you for some reason weren’t listening to me, here’s your perfect opportunity. There’s not a single issue of Criminal or Incognito for over the price of $1.50. What are you waiting for?
