This study seeks to understand how sales incentives and emotional shopping drives foster unplanned purchases that strengthen long-term customer relationships. Research Methodology: Quantitative method was used in this study with individual analysis units, and data collection was done through a questionnaire with a valid sample of 400 respondents.

Results: The findings indicate that both sales promotion and hedonic shopping motivation significantly influence impulse buying behavior. In turn, impulse buying positively and significantly contributes to customer loyalty. Sales promotions also directly enhance loyalty, while hedonic motivation demonstrates both direct and indirect effects through impulse buying. The model achieved strong predictive relevance, with R ² values of 0.459 for impulse buying and 0.415 for customer loyalty. Conclusions: Sales promotions and hedonic motivations play crucial roles in shaping impulsive purchase tendencies, which increase customer loyalty. The TikTok Shop benefits from strategic promotions and the emotional appeal of shopping experiences to retain customers in a competitive social commerce landscape. Limitations: This study focused only on fashion product buyers within the TikTok Shop in Indonesia, limiting generalization to other product categories or platforms. Contribution: This study contributes to the e-commerce and consumer behavior literature by integrating hedonic and promotional factors with loyalty outcomes, offering managerial insights for optimizing digital marketing strategies.]]>
