I interpreted the OP as he went into a fly shop to buy some shot, a fairly simple premise, and upon realizing the only option was lead free for $15, decided that was above where his personal supply and demand curves intersected for that particular product. I didn’t read into it beyond that. And as noted, there are places where you can buy shot, not specifically marketed for FFing, at much more reasonable prices, and I’m sure the OP will seek out those options in the future. It’s funny. Market the same splitshot to the opening day crowd and you can charge about $4 for it. Market it to FFers and apparently you can charge $15. I’m not sure exactly what that says, but it’s probably not good.
As far as gas lawnmowers, I just like them, and enjoy cutting my lawn with them. Especially Honda’s. Nothing more to it than that. You mow with what you like, and I’ll mow with what I like, as long as it’s legal to do so.
