| Abstract: | Traditionally, relationship marketing focuses upon the interaction between suppliers and consumers. In this article, the authors propose that relationship marketing cannot ignore another type of (long-term) interaction: the one between consumers and products. Both types of interaction should be taken into account when assessing the nature and the quality of the relationship. The relevant literature on consumer–product interactions is limited. Existing theoretical concepts, including brand loyalty, cannot adequately cover the full notion of consumer–product interactions. Acquisition pattern analysis (APA) seems capable of providing an alternative. It provides an insight in the structure of product sets and acquisition orders. However, the available techniques for APA cause confusion by their emphasis on either the structure or the order of product acquisitions. The authors propose a methodological improvement, which has analytical implications as well. A study on purchases of financial products demonstrates the proposed alternative approach, and managerial implications are discussed. |
