Consumer evaluation of multi-product bundles: An information integration analysis

Consumers' reactions to multi-product bundles — two different products sold for one price — were obtained by systematically varying the attributes of both the primary product (e.g., VCRs) and the tie-in product (e.g., videocassette tapes). Respondents were given written product descriptions as well as the opportunity to inspect the actual products before responding. The results across a variety of dependent measures suggest that evaluations of the primary product and the tie-in product are averaged or balanced when evaluating product bundles. Furthermore, attributes of the tiein product had a much larger effect on the evaluations of product bundles than would be expected on the basis of their monetary worth alone. Other aspects of our results suggest that product bundling as a marketing strategy compares favorably with the use of cash rebates, especially when the bundle is enhanced by including a high-quality tie-in product.
