Ain't never met a rich tackle shop owner, at least not in the last 20-30 years. They do it 'cause they love it, and meybe us, (well SOME of us)

.
NIB is right even the price of hooks (quality ones) is getting whacked. Custom plugs, even if you make them, using quality hardware, and material + BIG $ And some of the stuff selling is junk, pure and simple.
I would like to know how much of the increase of tackle, is due to the resurgence in popularity of SW fishing..... the 'ol supply and demand thing.... I think the manufacturers know that you make hay while the sun shines.
