Assumptions Besides types of promotions, the impact of product involvement on consumer will also be investigated. The level of personal relevance of the product to consumers is considered as product involvement. In other words, involvement is the result of the interaction of consumers with products. 15 For example, a car or a bottle of perfume can be both considered as high-involvement products: the car is associated with high perceived financial risk, while perfume is perceived high social risk”. Product categories chosen for the study are assumed to show different degrees of involvement. Regarding the methodology, it is assumed that involvement, and utilitarian/hedonic benefits are reliable variables to measure their effect on brand loyalty. It also assumes that all interviewees frankly answer the survey questions; the statistical software and analysis methods applied were appropriate.
