This study was conducted to ascertain the relationship between the females' in-store purchasing decision process and the promotional mix. Two cosmetic salesmen groups were interviewed by using focus group interview technique to understand females' buying decision process with in-store promotional mix. The results indicated that females with buying intention will improve the effectiveness of in-store promotional strategies. The purchase behavior stimulated by in-store promotions was related to customers' emotional motivation. Finally, different in-store promotional activities would induce different psychological feelings.
