UPDATE: I did it. Signed up for the Amazon Comics Newsletter. Received a “code for a Free Download of Superman No. 1” via email, clicked the link, entered the code, and look, on my screen, it’s not a bird, it’s not a plane, it’s a digital Superman comic, which in this case means this particular issue of Superman from 2011. (Just so you know what you’re getting for free.)
Amazon would like you to read comics on a Kindle Fire, but if you don’t have one you can read the issue in a web browser. I think you can read it on the old school Kindle but I’ve never tried and it won’t be in color, of course. (Great Rao, I said “old school Kindle“.) When I checked out, no mention was made of reading Kindle comics using the Kindle app on an Android device. Nor is there any mention made of reading them on an iPhone or iPad.
Anyway, I got my free comic. Or more accurately received a license to read said comic digitally. Was granted a license to read the comic? Something like that. Only Jor-El knows for sure. If you want your freebie, click the link below.
