The research presented in this article provides evidence that add-on features sold to enhance a product can be more than just discretionary benefits. We argue that consumers draw inferences from the mere availability of add-ons, which in turn lead to significant changes in the perceived utility of the base good itself. Specifically, we propose that the improvements supplied by add-ons can be classified as either alignable or nonalignable and that they have opposing effects on evaluation. A set of four experiments with different product categories confirms this prediction. In addition, we show that the amount of product information available to consumers and expectations about product composition play important moderating roles. From a practical standpoint, these results highlight the need for firms to be mindful of the behavioral implications of making add-ons readily available in the marketplace.

Existing evidence suggests that preferences are affected by whether a price is presented as one all-inclusive expense or partitioned into a set of mandatory charges. To explain this phenomenon, we introduce a new mechanism whereby price partitioning affects a consumer’s perception of the secondary (i.e., nonfocal) benefits derived from a transaction. Four experiments support the hypothesis that a partitioned price increases the amount of attention paid to secondary attributes tagged with distinct price components. Characteristics of the offered secondary attributes such as their perceived value, relative importance, and evaluability can therefore determine whether price partitioning stimulates or hinders demand. Beyond its descriptive and prescriptive implications, this theory contributes to the emerging notion that pricing can transform, as well as capture, the utility of an offer.
