Free trade involves a principle of free will. The buyer should be able to decide to whom he wishes to sell and on what terms, and if the seller does not accept those terms then the buyer should be able to refuse to deal with him. Manufacturers can have many good reasons for choosing to price goods at different levels in different countries, such as their wish to build a long-term brand preference by cheaper initial marketing in a developing economy, or their desire to maintain an aura of exclusivity in mature markets through high pricing and confining sales to specialist retailers. Grey imports result in the manufacturer/ distributor effectively losing some, and often most, control of their pricing and retailing strategy in the importing country. This reduces their capacity to position the brand as they see appropriate. In extremis, a company can be put out of business in one nation by its own operations overseas!
