The objective of this article is to identify the determinants of saving decisions on fixed deposits. The effect of customers' prior experience with Non-Bank Finance & Leasing Institutions (NBFLI) has been investigated as a mediation factor. Structural Equation Modelling (SEM) in AMOS has been used to analyze the results and confirmed the results by using the bootstrap technique of SEM. The results show that the stability of the NBFLIs, security for the fund, interest rate of the fixed deposits, and quality and reliability of the service directly affect the decision to save fixed deposits. The institution's geographical location has not directly affected the decision on fixed deposits. The factors of the security, interest rate, quality, and reliability of the service have an indirect effect on the decision of saving fixed deposits with prior experience, except for the factor of stability of the institutions.

In Indonesia, motorbikes dominated public transit, making motorcycle sales extremely competitive for a number of brands, particularly Honda and Yamaha. The goal of this research is to identify and assess the effects of pricing perspective qualities, brand advantages, media branding, promotions, after-sales guarantee, products, colors, and designs, as well as fuel consumption as motor product items on consumer behavior. Purposive sampling was used in this investigation, with a total sample size of 194 participants. Using SPSS software, descriptive analysis and multiple linear regression analysis were used to analyze the data. The findings show that Honda's products play a larger role in the execution of its marketing plans, accounting for 87.75 percent of the total, with Yamaha's quality accounting for the remaining 79.40 percent influenced by other factors. This shows that respondents choose motorcycles with the following criteria: Engine, Media Branding, Price, Advertising and Fuel Consumption affect consumer behavior to buy both Honda and Yamaha products.  

With the increasing awareness of health and the widespread adoption of social media advertising, health food advertising has become an important source of information influencing consumer decision-making. However, existing studies have primarily focused on the effects of attitudes or behaviors, with limited attention to the underlying psychological mechanisms. Therefore, this study applies optimal arousal theory to examine how expertise and trustworthiness in health food advertising influence consumers’ purchase intention through perceived information relevance. The findings indicate that both expertise and trustworthiness positively affect perceived information relevance, which in turn significantly enhances purchase intention. These results suggest that individuals tend to pursue an optimal level of stimulation, and when advertising information evokes an appropriate level of psychological arousal and aligns with personal needs, it is more likely to facilitate positive behavioral responses. In addition to confirming the importance of perceived information relevance, this study extends optimal arousal theory from the level of sensory stimulation to the cognitive level, thereby advancing the development of optimal arousal theory research.

This study mainly aimed to examine the impact of university students' purchasing tendency from e-commerce sites and demographic characteristics on student satisfaction through the example of a leading foundation research university in Türkiye. In the study, it was investigated whether there was a significant difference between students' purchasing tendencies from e-commerce sites and student satisfaction. It was also investigated whether there was a significant difference between demographic characteristics and student satisfaction. Methodologically, a descriptive online survey method including a questionnaire was applied to collect data. The survey was responded by 240 randomly selected students. The data were analyzed with SPSS-26. The study concluded that there was no significant difference between the average daily time spent on the internet and the type of device used to connect to e-commerce sites, which are among the criteria reflecting the tendency to purchase from e-commerce sites, and student satisfaction whereas there was a significant difference between the number of products purchased through e-commerce sites and student satisfaction. Furthermore, it was revealed that there was no significant difference between demographic characteristics such as gender, marital status, education and monthly income and student satisfaction, whereas there was a significant difference between age and student satisfaction. Accordingly, it was indicated that the difference in terms of age was especially in favor of students in the 22-25 age group. It is thought that the study will contribute to the literature by examining the impact of university students' purchasing tendency from e-commerce sites and demographic characteristics on student satisfaction, together with the example of a leading foundation research university. The study is limited by the selected sample foundation research university, the number of students responded, survey questions-answers, the applied statistical analysis methods and tests. Therefore, in order to reach more general results, it is suggested to expand the studies with more diverse and larger numbers of foundation research universities, students, survey questions and statistical methods.

This study investigated the factors influencing consumer repurchase intentions of beauty and haircare products on e-commerce platforms in South Africa. With the growing trend of online shopping, understanding the determinants of repurchase intention became essential for businesses looking to retain customers. The purpose of the study was to explore how various factors such as brand trust, security risk perception, ease of use, customer readiness, and loyalty impact consumer repurchase behaviour. A quantitative research design was employed, using an online questionnaire to collect data from 164 respondents who had previously purchased beauty and haircare products on an online shopping site for cosmetics in South Africa. The study utilised multiple regression analysis to assess the relationships among the identified factors and their influence on repurchase intentions. The findings revealed that brand trust, ease of use, and customer loyalty were significant positive predictors of repurchase intentions, while security risk perception had a negative impact. Readiness did not show a significant relationship with repurchase intentions. Based on these results, the study recommends that e-commerce businesses in the beauty sector focus on building trust, enhancing user-friendly interfaces, and fostering customer loyalty programs to encourage repeat purchases.

This study provides a comprehensive analysis of the marketing mix strategies that influence customer acquisition at Spar in Durban. Utilizing a quantitative methodology, data were collected through structured questionnaires completed by 278 respondents. The findings indicate that Spar effectively employs digital marketing tools—including social media, WhatsApp, and loyalty programs—as key communication channels to engage customers. Reliability analysis confirmed the validity of the measurement instrument (Cronbach’s ? = 0.902; KMO = 0.899). The results demonstrate that younger consumers are more responsive to digital platforms, particularly social media and loyalty programs, while traditional methods such as printed flyers are less effective. No significant differences were observed in the perceived effectiveness of specific digital channels across different respondent groups, suggesting a consistent perception of Spar’s digital engagement. The study emphasizes the importance of integrating digital strategies with factors such as pricing, convenience, and product assortment to enhance customer acquisition in Durban’s competitive retail environment.
