The 407's Lauren Margolis steps inside Acme Superstore in Longwood. It is one of the largest comic book shops in the country! May 2 is Free Comic Book Day and fans will be lining up for goody bags full of fun items and of course comic books. This year’s event is more than just free reading material. Acme is amping up the excitement with 500 mystery grab bags and a random golden ticket for a pair of Gorillaz tickets at the Kia Center.
