Purpose This study aims to assess factors influencing customers' online grocery shopping experiences, and it evaluates the central role of customer service and consumers' responses to satisfying grocery shopping. Design/methodology/approach A mixed-methods approach was used; linguistic inquiry and the word count (LIWC) method captured qualitative aspects of consumers' grocery shopping experience, whereas partial least square-structure equation modeling tested hypotheses regarding antecedents to consumers' overall online grocery shopping experience. Findings The PLS-based analysis confirmed the qualitative insights, establishing the significance of customer service, which accounted for 68% variance in the overall experience and 42% variance in customer satisfaction, along with other experience antecedents such as website, product and delivery. Originality/value Responding to the call for a better understanding of customer service, this study brings out the challenges online grocery shoppers are facing in terms of customer service and empirically establishes customer service as a key driver of customer experience, thereby extending the earlier work on customer service and online customer experience.
