Supply and demand.... really! Ok, maybe because of the fairly few Kinetico dealers.

"... to make the most money...". I don't agree. The largest, most successful and profitable retailer in the world is Wal Mart. They did not get there by charging the most for the products they sell as Kinetico dealers do.
Gary:
For the record, Walmart sucks and I refuse to shop there! If you think the ideal business model is being the cheapest, then let's look at the discount retailers and the wake of dead bodies. Hmmm ... Caldor, Bradlees, Ames, Grants, Montgomery Ward, Woolworths, should I continue or do you get the point. Never, Never compete on price only ... knowledge, service, etc gets the order. If you try to get every order (with the lowest price strategy), then you are doing something wrong. BTW, I shop at Targets and willing to spend more.
