A firm may choose to offer a high-quality brand and sell it at a high price to appeal to a particular quality-conscious MARKET SEGMENT; or to produce a lower-quality brand to sell at a lower price to a more price-conscious segment. In terms of PRODUCT POSITIONING a firm, for example, may choose to upgrade slightly the quality of its brand and offer it at an unchanged price to make it more competitive; alternatively, the firm may modify a low-quality, low-price brand by significantly upgrading its quality and offering it at the same price to appeal to a new medium-quality price-conscious segment. Businesses often offer several different qualities or specifications of a product as a product line in order to appeal simultaneously to several market segments.
