This study examines how key store attributes influence shoppers’ purchase intentions and, ultimately, customer satisfaction in five selected supermarkets in Cavite, Philippines. Store attributes—defined as accessibility and cleanliness, product assortment, promotion, price, and customer relations—are hypothesized to drive the likelihood that a customer will buy (purchase intention) and feel satisfied. Employing a quantitative correlational design, the researchers administered an adaptive, 45-item Likert-scale questionnaire (4-point) both face-to-face and online to 380 supermarket patrons. Instrument reliability was confirmed via Cronbach’s alpha coefficients between 0.8740 and 0.9379 (good–excellent). Respondent demographics indicated a predominantly young (18–28 years, 75.5%) and female (62.4%) sample, with over half (51.6%) reporting a monthly income below ₱10,000. Descriptive analysis (frequency, percentage, weighted mean, and standard deviation) revealed that accessibility and cleanliness received the highest effectiveness rating (mean = 3.44, SD = 0.43), while customer relations scored lowest. Inferential analysis using Spearman’s rank-order correlation showed a moderate positive relationship between purchase intention and customer satisfaction (ρ = 0.549, p < 0.001). Among individual attributes, promotion correlated most strongly with purchase intention (ρ = 0.507), and price exhibited the highest link to customer satisfaction (ρ = 0.567). These findings suggest that supermarkets seeking to boost sales, and loyalty should prioritize promotional strategies to drive purchase intent and calibrate pricing structures to enhance satisfaction. Optimizing accessibility, cleanliness, and other in-store factors can further improve customer experience, yielding competitive advantage in the retail sector.
