I enjoy reading them, but they just cost too much now.
When I started detecting (granted, it was almost 40 years ago), a subscription was about five dollars a year.
Also, I have hundreds of old treasure magazines that, except for the new detector reviews, have about the same stories that they are publishing now.
I'm afraid that the double whammy of higher prices, and internet discussion boards like this one, have really hurt the circulation of all periodicals - not just treasure magazines.
