We will not buy certain brands, regardless of price or promised quality. Some factors who previously had choice of brands now only carry the budget. We are fortunate in that we have a surplus of factors competing, the only way forward for them is to supply quality at a better price than dealer. What worries me is if they all fall. If the dealers have monopoly trade clubs and prices will come to an end, we all know what they can charge for stuff you can't get anywhere else.
