Why have you taken money for it already then, when there is not product yet?
What country are you from, Dansker? I don't know about other countries, but at least in the USA it is common practice to sell what is called "subscriptions". It is basically pre-ordering and reserving a fixed amount of issues to be delivered at a later date.
I support bitcoin magazine and tried to increase my subscription unsuccessfully
However, I will say when I bought my issue in January, the website led me to believe the magazine was ready for distribution. Maybe until it is ready, you could update the website orders to be more clear that the magazine is still under construction?
Also if you want more of my money, let me know how I can give it to you.
