Free Comic Book Day is a single day - the first Saturday in May - when participating comic book shops across North America and around the world give away comic books absolutely FREE* to anyone who comes into their stores.
The site offers a store locator for all y'all who may not know where the local comic shop is.
Last year comics from 40 different publishers were available. All the big guns like DC, Marvel, and Image showed up in force giving away a big variety of books and swag. There are plenty of smaller publishers like Dynamite (who is doing a bang up job on the Lone Ranger series) and independents like Radical Publishing.
So go ahead and visit your local comic shop. Take the kids. Get some free stuff.
