Update: Amazon’s running its own one-day sale now on a lot of the same titles, and they seem to be even cheaper.
I was never a comic book person growing up, though I was and still am a Star Wars person. But there’s no sense in not digesting everything that has the Star Wars name on it for the sake of staying a purist. Some canonical literature is fan fodder, and some is really, really good. Find what you like during this massive Star Wars sale from comiXology and prepare for your Last Jedi viewing in a different way.
