Product lining and Price 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.

The number of different product lines sold by a company is referred to as width of product mix. The total number of products sold in all lines is referred to as length of product mix. If a line of products is sold with the same brand name, this is referred to as family branding. When you add a new product to a line, it is referred to as a line extension. When you add a line extension that is of better quality than the other products in the line, this is referred to as trading up or brand leveraging. When you add a line extension that is of lower quality than the other products of the line, this is referred to as trading down. When you trade down, you will likely reduce your brand equity. You are gaining short-term sales at the expense of long term sales.

Image anchors are highly promoted products within a line that define the image of the whole line. Image anchors are usually from the higher end of the line's range. When you add a new product within the current range of an incomplete line, this is referred to as line filling.

Price lining is the use of a limited number of prices for all your product offerings. This is a tradition started in the old five and dime stores in which everything cost either 5 or 10 cents. Its underlying rationale is that these amounts are seen as suitable price points for a whole range of products by prospective customers. It has the advantage of ease of administering, but the disadvantage of inflexibility, particularly in times of inflation or unstable prices.

There are many important decisions about product and service development and marketing. In the process of product development and marketing we should focus on strategic decisions about product attributes, product branding, product packaging, product labeling and product support services. But product strategy also calls for building a product line.

The product mix includes all the product lines and items that the library makes available. The product line is a group of closely related products such as different kinds of genre reading or the different services for seniors. The product mix has length, width, and depth.

Length is the number of product lines--collections and services.

Width is the number of categories within a product line such as the SF or large print collections or the number of services for adults.

Depth is the number of copies for each item or the number of times that a service is available.

Thus the product mix can be expanded by adding length or new product lines, width of a new category to an existing product line [graphic novels], or depth [adding more copies to make particular content more accessible.
