Our theoretical model demonstratesthat product uncertainty affects purchase intentionthrough lifestyle fit uncertainty. Thus, we introduced amore important predictor to online transactionliterature. Third, this paper contributes to uncertaintytheories by explaining “what” affects uncertainty [36].We integrate MECL theory, SCL theory and productuncertainty theory [2, 9, 23] to identify threecomponents of IT-mediated lifestyle-centric marketingservice content as the antecedents of lifestyle fituncertainty and product uncertainty. Finally, ourtheoretical model also extends uncertainty literature byexplaining “why” and “how” two ICT-enabledinformation retrieval capabilities, as moderators, helpreduce consumers’ lifestyle fit uncertainty online [36].
