Post Purchase Behavior is the feelings or perception a purchaser or buyer has after buying a product or service. Depending on the consumer’s satisfaction/dissatisfaction s/he may repurchase or discontinue the service or product.
What determines whether the buyer is satisfied or dissatisfied with a purchase? The answer lies in the relationship between the consumer’s expectations and the product’s perceived performance. If the product falls short of expectations, the consumer is disappointed; if it meets expectations, the consumer is satisfied; if it exceeds expectations, the consumer is delighted. This suggests that sellers should promise only what their brands can deliver so that buyers are satisfied.
