product lining

Product lining is the marketing strategy of offering for sale several related products. Unlike product bundling, where several products are combined into one, lining involves offering several related products individually. A line can comprise related products of various sizes, types, colours, qualities, or prices. Line depth refers to the number of product variants in a line. Line consistency refers to how closely related the products that make up the line are. Line vulnerability refers to the percentage of sales or profits that are derived from only a few products in the line.
