Being 75 years old I was late to the digital scene. I subscribe to at least 4 modelling magazines and buy several others. I has some bad experiences using several digit based publications. Because of how poorly the Covid-19 issue was handled here in the U.S. my bookstores were closed. The only way I could get by U.K. based Air International and Air Forces Monthly Magazines in anywhere near a timely manner was to change my subscriptions to digital. The Key Aero publications are easily downloadable and as PDF files, can be saved for future reference. As a modeler that is important to me. I also save money over paper subscriptions.
Now on that same comparison I buy Scale Aircraft Modelling at Barnes and Nobel with about a month's delay. I was also buying Scale Aviation Modeller International. I tried their digit issue and found it hard to use or download. I contacted them and got a paper subscription because they said the mail was much better now. I did this because Barnes and Nobel just got their August/September issue in last week(December 2021). I did this on 11/11/2021 and am still waiting for my first issue.
One further question my own mind. How come EVERY major mail ordering company in the US offers all the above PAPER copies on a real time basis while the biggest book seller in the country can't seem to get them even close to on time.
