This study examines the effect of online promotion and product quality on consumer buying interest at Fenny Aneka Shop Palu. Primary data were collected by questionnaire from 75 consumers selected through purposive sampling and analysed using multiple linear regression. Online promotion and product quality each have a positive and significant effect on buying interest, and jointly explain 31.2 per cent of its variance, with online promotion carrying the larger coefficient. Online promotion widens market reach and gives a more interactive, personal experience, while good product quality raises consumer trust and encourages repeat purchase and recommendation.
