sales method
It may be that selling vacuums by in home demonstration is a dying breed. Buying on line is definitely taking its tole on store chains such as Sears and Masey's, it may be killing door to door sales as well. One problem with this sales approach is that it inflates the price of the product, in order for everyone to get their share of the profit. This is one reason why you see so many Electrolux, Filter Queen, Kirby, and Rainbow vacuums being sold refurbished. I do believe that a company has the right to sell their product in the method they choose, but at the same time, you also have to sell it in the way the consumer wants to buy it, if not, they will go elsewhere. I think back in the 1980's, Aerus, still Electrolux back then did sell their vacuums in stores for a while. Also, it would be interesting to know how much competition the Sirena has been to Rainbow.
