There are a lot of digital bargains running around in this post-SDCC week, and some new digital releases that look tasty as well. Let's start with a good one that won't last: ComiXology is having a Superman 101 sale, starting at midnight (EST) on Friday, and running through Sunday. You can brief yourself on the Man of Steel with 99-cent issues of Action Comics #1 (Superman's debut), The Man of Steel #1-6, Superman: Secret Origin #1-6, and more including the first appearances of Jimmy Olsen, Lex Luthor, and Supergirl.
In case you missed it in the rush of SDCC news, Dark Horse is now releasing Star Wars comics on its digital app, and they are posting Star Wars: Knights of the Old Republic #1 and Star Wars: The Clone Wars #1 for free to celebrate.
New free comics on comiXology include (links are to the comics on their web reader): Batman: Gotham Knights #1, Impulse #1, Robin #1, Titanium Rain #1, and a bunch of previews. And there's the third chapter of the Rise of the Planet of the Apes prequel from BOOM! Studios—the whole thing is free, so you might as well go back and get the earlier chapters as well.
Here's another SDCC announcement you might have missed: Square Enix, publisher of such fine manga as Black Butler, Fullmetal Alchemist, Higurashi When They Cry, and Soul Eater, is offering one free volume 1 through August 10. The details are here.
If you're in the mood for some Deep Thoughts, Wiley is offering the book Superheroes: The Best of Philosophy and Pop Culture as a free e-book on a number of different platforms, including iTunes, Nook, and Kindle.
Finally, here are a couple of SDCC manga deals that will be running out soon: Viz is taking 40% off its volume 1s to celebrate the rollout of its web app, and Yen Press is offering volume 1s of its manga, including Yotsuba&!, Maximum Ride, and Highschool of the Dead, on its iOS apps for $2.99
