Free Comic Book Day was the 368th post on OzBargain over 10 years ago and is still going. FCBD is held on the first Saturday in May every year where people are invited to go to their local comic book store to pick up a free comic book. These are physical books, not electronic.
FAQ. Each stores policy is different but at a minimum you will get 1 free comic. For example, Minotaur in Melbourne will be giving out 5 comics per person all day. The 1st 150 customers will also get a goodie bag. Kinokuniya in Sydney are giving out showbags with 4 comics included. So check your local comic book store's website/Facebook for more info.
