We almost missed this one and with one hour left in the promotion it isn’t much notice. You must sign up for a (free) Comixology account to get on the list to receive a free code starting Thursday, April 11, 2013 to begin selecting your free issues for digital download (digital downloads available only). Comixology is the website most comic book shops use to manage pull lists. There is no obligation ($) to sign up for this promotion.
But you must act right now as the deadline is 11:59 Eastern, Tuesday, April 9, 2013–one hour from when this post is going live!
