The title speaks for itself. The Walking Dead: Vol 1 (issues 1-6) graphic novels are now available on Kobo. Here's the link: http://www.kobobooks.com/ebook/The-W...w4A/page1.html
Better yet, they're non-agency so are available for Kobo's discount codes! I was just about to buy them from ComiXology for the same price, so the discount code was a big bonus. Can't wait for the next volumes.
Though amusingly, issues 5 and 6 were reversed, someone screwed up while operating the scanner.
I imagine they'll update it at some point.
