Apparently someone is selling Harmy’s Despecialized versions at Wizard World St. Louis Comic Con.
$30 a piece
While this is irritating, it’s kind of par for the course with conventions. You could report the seller to the people in charge of vendors at the convention, but in my experience, they’ll pretty much just ignore you. They’re pretty small fish to fry in the grand scheme of things. Bootlegs at conventions have been going on since the earliest days of comic con.
Even though this could be risky, perhaps you could call the police and have them arrest the bootleggers as that would put a stop to it.
