A consumer can be understood as the final user of goods or services, someone who purchases products not for resale but for personal use or satisfaction. Every individual, whether buying a simple snack or making a major investment like a car, acts as a consumer in different contexts of life. What makes consumers interesting to study is that their choices are rarely random; instead, they are guided by a mix of psychological triggers, social influences, and economic conditions. Consumer behavioural patterns usually follow a certain flow. It begins with recognizing a need, such as hunger, comfort, or status. From there, consumers actively or subconsciously evaluate options comparing prices, checking quality, seeking reviews, or even asking family and friends for opinions. Personal attitudes, habits, and emotions play a big role here. For instance, a familiar brand may feel more trustworthy, while an attractive advertisement or a friend’s recommendation can sway a decision toward trying something new. On top of that, factors like income level, cultural background, and lifestyle shape how much weight a consumer gives to quality, price, or social approval. The present research builds on these ideas by exploring how psychological and behavioural factors work together in consumer decision-making. Rather than limiting the focus to one type of product, the study looks across different price ranges and categories to reveal patterns that often go unnoticed. By examining high-stakes decisions alongside everyday purchases, the research aims to show a clearer picture of why people buy what they buy. These insights not only help marketers refine their strategies but also guide policymakers in protecting consumer rights and give everyday shoppers a better awareness of their own buying habits.
