Already get the magazine? Move on. – Astronomy Magazine Review

If you thought, like I did, that this had ANY relationship to the magazine subscription you currently enjoy, well, like me, you were mistaken. This is just a second way to purchase another digital subscription of the same magazine you already enjoy reading on paper every month. Don't bother looking for any way to link up your paper subscription, or do anything associated with it. This is just a standalone app to let you purchase individual issues or a subscription, but this is a separate disconnected subscription from what you may have now. And to the reviewers saying "just email them and tell them you're a print subscriber and to turn on digital", they aren't going to do that for free. Astronomy is a small circulation magazine to begin with - they charge their own subscribers right NOW if we also want a digital version. Bottom line - if you don't get the magazine at all, the may be a valid way to do it, but that's it.
