I get Asimov's magazine and strip the DRM after downloading from Amazon. Calibre converts it nicely whether starting with Kindle or epub. Sibling reads it on my Nook ST without a problem (epub) while I read it on the Fire or Voyage. You want to be sure that wherever you DO source it that you can strip the DRM and store on your computer. In the past, both Amazon and B&N would 'drop off' issues more than a couple of years old. Amazon has since restored those old issues but B&N never did. This was a problem for me as sometimes I get very behind on these magazines and other times, I want to keep it because it had some good stories I would like to reread. I hope one day to figure out how to excise out the stories I want to keep and make like a personal anthology of them.
According to this page, you can have it delivered to your Kindle, Kobo or Nook device.

When you load into Calibre, you need to change the date of the issue, or it will keep replacing it thinking it's the same issue.
