The document summarizes the buyer's decision-making process when purchasing a refrigerator. It involves 5 stages: need recognition due to increased family size or income, information search through internal research and external sources like friends and ads, evaluation of alternatives by online comparisons or visiting multiple stores, evaluation of key criteria like price, power consumption and brand loyalty, and finally the purchase decision between purchasing immediately or continuing to search. Higher income groups prioritize design and technology over just fulfilling basic needs. Brand loyalty and aesthetic factors also influence the decision.
