Man, this is hard! I didn't know there would be tests.
I think he is implying that pipes are way overpriced and a rip off. But my answer to that is it depends on what the market will bear (and what market you are in), the level of craftsmanship (got a way to go) and you have to turn a profit for all your hours of labor, otherwise, why do it? Poverty? Then there is mark-up selling wholesale, finding an importer to buy your pipes and advertise, etc., Everybody's got to make some money.
Anything is MUCH cheaper if you can do it yourself.
Or maybe I just totally missed the point.
