Lest we forget (and I'm aware that many of us do not know this because we were born after buying top quality rods in shops became the norm) that until the late 1960's-early 1970's quality rods were bought directly from the manufacturer. And you had to pay for the rod upfront and then wait the 3 months to 2 years before it got to your hands from the time you ordered it.
The two friends I had that owned shops (they are both retired now) sold everything from tying thread at $1.00/spool to high end rods at $500.00+. Guess what they made the majority of their yearly profits on? Right, the fly tying materials, waders, fly lines, leaders, flies, clippers, etc. In other words, the vast majority of their yearly income was not from rod sales.
