Beyond promotion-based store switching: Antecedents and patterns of systematic multiple-store shopping (revised version).

In this paper, we demonstrate both theoretically and empirically that single-purpose multiple store shopping is not only driven by opportunistic, promotion-based motivations, but may also result from a longer term planning process based on stable store characteristics. We find that consumers may systematically visit multiple stores to take advantage of two types of store complementarity. In the case of 'fixed cost complementarity', consumers alternate visits to high and low fixed cost stores to balance transportation and holding costs against acquisition costs. 'Category preference complementarity' occurs when different stores offer the best value for different product categories, and may induce consumers to visit these stores together on combined shopping trips. In both cases, multiple store shopping leads to a shift from share-of-customers to share-of-wallet retail competition.Multiple store shopping; Spatial competition; Store choice; Planning; Processes; Characteristics; Complementarity; Cost; Costs; Category; Preference; Value; Product; Shopping trip; Competition; Choice; Patterns;

Shelf Sequence and Proximity Effects on Online Grocery Choices

Research on traditional store shelf effects has shown that a product’s absolute and relative shelf position may strongly affect consumer choices. In this paper, we examine whether such shelf effects are still at play in an online grocery store. While traditional ‘eye-level’ placement is no longer predominant, we find that a product’s choice probability increases when presented on the first screen or located near focal (highly-preferred) items. Our results further demonstrate that these primacy and proximity effects depend on assortment size and composition. Larger and more difficult to process assortments complicate the choice process, thereby stimulating the use of shelf-based simplifying choice heuristics.marketing ;

Beyond promotion-based store switching: Antecedents and patterns of systematic multiple-store shopping.

In this paper, we demonstrate that single-purpose multiple store shopping is not only driven by opportunistic, promotion-based motivations, but may also be part of a longer term shopping planning process based on stable store characteristics. We find that consumers may systematically visit multiple stores to take advantage of two types of store complementarity. In the case of 'fixed cost complementarity', consumers alternate visits to high and low fixed cost stores to balance transaction and holding costs against acquisition costs. 'Category preference complementarity' occurs when different stores offer the best value for different product categories. Tying these multiple store shopping motivations to characteristics of grocery stores leads to interesting new insights into the nature of spatial retail competition.Category; Characteristics; Choice; Competition; Cost; Costs; Multiple store shopping; Patterns; Planning; Preference; Processes; Product; Spatial competition; Store choice; Value;
