the refusal of manufacturers to do business with companies who sell cheaply has been in practice for a long time.
the most noted is the perfume industry who refuse to sell to supermarkets who then under cut traditional department stores, they see the selling of their perfume at a cut price as undermining their image of being exspensive..... but worth it
until the nineties pharmaceutical companies would only sell through the more expensive pharmacy's.... again not selling to supermarkets who would sell cheaply, their was an actual law in place stopping supermarket selling over counter medication which kept the price of these items artificially high. it was the change in this law that is said to be responsible for over 70% of pharmacies closing in the last 10yrs
the refusal to sell to companies who help under-value our industry might not be a bad idea
