whether important others think one should or should not expend the effort to clip, save, and use coupons". The consumer's behavior intentions are influenced by their personal beliefs about coupon usage, meaning whether or not they think saving money is important and are willing to spend the time clipping coupons. These potential beliefs also influenced the coupon user's thoughts about what others think about their usage of coupons. Together, the coupon user will use their own beliefs and the opinions of others to form an overall attitude towards coupon usage. To approach this study, Shimp and Alican surveyed 770 households and measured the aspects of the TRA model in terms of the participant's responses. The received responses indicated that consumers' norms are "partially determined by their personal beliefs toward coupon usage, and to an even greater extend, that attitudes are influenced by internalizations of others' beliefs". Positive attitudes towards this behavior are influenced by an individual's perceptions that their partners will be satisfied by their time spent and efforts made to save money. Brand loyalty TRA has been applied to redefine brand loyalty. According to TRA, the antecedents of purchase behavior are attitudes towards the purchase and subjective norm. In 1998, Ha conducted a study to investigate the relationships among several antecedents of unit brand loyalty (UBL) by introducing TRA. Consumers are brand loyal when both attitude and behavior are favorable. In his study, Ha developed a table indicating 8 combinations of customers' brand loyalty based on their loyalty on 3 variables – attitude towards the behavior, subjective norm, and purchase behavior is loyal. According to Ha, marketing managers should not be discouraged by a temporary disloyalty and need to strive for grabbing brand loyalty when customers are showing loyalty to two of the three variables, but they need to rediagnose their customers' brand loyalty when customers are showing loyalty to only one of them. The main focus should be pointed at either enhancing the consumer's attitude toward their brand or adjusting their brand to the social norms. New research investigated norms in social media, contributing to TRA from a more updating perspective. Green Behaviors TRA has also been used to study consumer attitudes towards renewable energy. In 2000, Bang, et al. found that people who cared about environmental issues like pollution were more willing to spend more for renewable energy. Similarly, a 2008 study of Swedish consumers by Hansla
