I was at a craft fair in Tennessee once long ago. People were selling hand-turned bowls, fountain pens, textiles, pottery, etc. There was one seller whose products were quite different: bowls and things roughly hewn out of wood with the bark on and such. I think he styled himself as, and perhaps was, an Appalachian mountain man from eastern Tennessee (this was in Nashville, which is a bit like Las Vegas). I wasn't in the market for what he was selling, or really anything, but another oddity of his goods was the precision of their prices: $41.13 or $15.02 and so forth. Everything else had a price that ended in 0, 5, or 9, and generally it was a number of dollars with no cents, maybe just two significant digits. This gave me the impression he had very exact knowledge of his own costs and profit margin but very little sense of the pricing customs of craft fairs, or really pricing in general. Anyway, this is just an anecdote. His pricing didn't seem to be making him more prosperous, but he is one of the few things I remember from that day.
