The purpose of this study was to segment consumers based on sales promotion orientation and examine the differences between the consumer segments on shopping styles and demographics. A total of 462 responses collected from a questionnaire survey to subjects aged over 20 were analyzed. Cluster analysis on sales promotion identified four groups including rational group(21％), active group(28％), insensitive group(22.1％), and interest group(28.9％) of sales promotion. MANOVA, ANOVA and x²-test revealed significant differences among the four groups on shopping styles(high-quality prone, value prone, price prone, brand prone, fashion prone, hedonic shopping prone, and loyalty) and 4 demographic characteristics(i.e., age, marital status, occupation, and education). The rational group showed lower brand proneness than did other groups while the active group showed higher price and brand proneness. The interest group showed high value, brand, and hedonic shopping proneness while the insensitive group was the least engaged in shopping styles. The study developed a profile of each segment and provided marketing implications.
