I haven't bought a new hunting bow since about 1992. When I find arrows that fly well out of my bows, I generally buy 3-4 dozen shafts and enough fletching materials, etc. and they last me a LONG time. Many of my broadheads have several kills on them, and once again if I find something that flies well and I believe in, I'll get a bunch and stick with them. All told, this year I haven't spent one dime on these items.
I do generally lose a tab or two during the season and have bought a couple of those to replace them. In fact, I kind of feel guilty at shoots walking by The Nocking Point, Kustom King, or Three Rivers and NOT buying anything. But this season, I really haven't needed much of anything.
I really find myself at a point in my life of wanting to downsize my stuff. I don't have a ton of bows and many things I can't get rid of, but I've been going through a major reduction in the hunting clothing department, banking that my new Sitka Gear will be more versatile and outlast my previous closet full of stuff. And in selling most of the latter, my closet space has opened up tremendously (and packing for trips has been much easier).
Now spending money on tags, gas, etc., that's a different story. But I do think we traditional guys are a bit more frugal than our compound cousins in the archery equipment category. Either that, or our trinquets cost a lot less money than their releases, sight systems, expandable broadheads, new bow every year, etc. Sometimes I wonder how our traditional vendors can make a living because of that...but I'm glad they can because they are there when we need them.
