David Gabriel, Marvel SVP of Sales:
We’ve seen a tremendous response to the digital codes in Avenging Spider-Man, our Season One graphic novels and the Ultimate Comics line. The positive reactions from both retailers and fans make it clear that including these codes with our books drives customers into comic stores on a repeated basis.
Awesome move on Marvel’s part. With every $3.99 physical comic purchase, you get a digital version via the Marvel Comics App on Android or iOS. Leave it to a comics company to pave the way for a languishing publishing industry.
