Yes, I ordered my second Enfield from the back of "Boy's Life", the Boy Scout magazine, for $12.95 plus $2.00 shipping. The rural mail carrier leaned the box up against a tree inside the hedge, on the brick walkway to our house, where I could find it on the way home.
Even as late as 1993, I bought an SKS and an unissued FR-8 for $79.00 at Rose's Dime Store. I think the sight of those SKS's standing up in a cardboard drum triggered some childhood memory of the same marketing, and a sudden craving.
The general store in town, built in 1775, sold individual shotgun shells, for boys and others who could not afford $1.50 for a whole box.
