The moderating role of mobile promotion during current and subsequent purchasing occasions: the case of restaurant delivery services

Purpose This study aims to explore the moderating outcomes of mobile promotions in three parts. First, Study 1 is conducted to discover the moderating effect of mobile promotions when consumers initially purchase a restaurant service. Second, Study 2 investigates how the promotion level during subsequent purchasing events moderates the relationship between attitudes toward selecting a restaurant brand (ATRB) and repurchase intentions. Third, the study compares mobile promotion effects between the initial purchase stage and subsequent purchase state. Design/methodology/approach Two studies are conducted to test the hypotheses. Using a longitudinal survey, Study 1 demonstrates the moderating role of mobile promotions (M-promotions) during the initial restaurant choice stage (T). Study 2 extends these findings to the reordering stage (T+1). Findings The results of Study 1 show that price discounts are much more impactful than free delivery when food quality and online reviews are positive. Study 2 shows that price discounts have more substantial effects than gifts at time T+1 when ATRB is positive. The findings are relevant to both scholars and managers, adding insights to discussions on promotions arising from the evolution of consumption experiences. Research limitations/implications Promotions differ in financial value; hence, comparisons of promotional packages may vary during subsequent purchase states, helping to explain subsequent promotion stages and enabling scholars to understand their impact on the food reordering context. Originality/value The fact that no empirical studies have examined the roles of M-promotions during subsequent purchasing stages constitutes a significant gap in extant promotion research. Therefore, this study seeks to fill this gap by providing robust evidence to demonstrate these effects and related temporal mechanisms. Additionally, although the literature on promotion is used mostly in cross-sectional studies, this study addresses a common challenge to reveal dynamics of promotion levels during subsequent consumption periods.
