Many of you perhaps have been on this train for a while but I wanted to share with those of you who were like me and didn't think of this sooner. If you are an Amazon Kindle Unlimited member you get to "borrow" 10 books at a time for "free". (Actually you pay I think $10 per month but we have it anyway for the family.) It is not every book, just those marked KindleUnlimited. There are many great gun books on the free list including many of Massad Ayoob's books (even new ones), tactics, general history of firearms...lots of cool stuff. I guess I just didn't think there would be much there so I never looked. Now I'm catching up! Good opportunity for some training or other material at a good price, especially if your family already has this service.
