https://promo.marvel.com/ To get your pick at 700 free comics, you've got to go to the special promotions page above by 11:59 EST on April 9 to sign up for the offer. Then, starting April 11, you'll get an invite via e-mail that will lead you back to the Marvel Comics app to select any of the free comics you might want. Presumably, the selection will be similar, if not identical, to what was offered last time. They are sending invites to readers in waves -- so as not to brick the whole system again -- so don't worry if you don't get your invite exactly on April 11. That said, you only have 48 hours from the time you receive said invite, so don't procrastinate. Go sign up! Get free comics!
