Scheduled to take place between July 15 and September 9, comic shops will receive five to six Free Comic Book Day (FCBD) titles in their weekly shipments during each week of the promotional window. Release of these titles may vary from shop to shop, as retailers are encouraged to release the books as they see fit for their unique circumstances. Retailers may release one free title a day, may make all of that week’s free titles available at once, or any other plan that works for them. Free Comic Book Summer is designed to be flexible and customizable so retailers and fans can get the most out the event.
