Price: The price factor is another important variable to be included in demand analysis. Here one has to consider the prices of the product and also its substitute and complements one may also consider the price differences between the product concerned and its substitutes and compliments.

Price as a determinant of the volume of sales of consumer non durable is sometimes more important through cross elasticity ( involving substitute products) than it is directly in terms of price elasticity. Direct price elasticity can expected to be more important with respect to those consumer non durables which are capable of storage and are freeform risks of changes in styles.
