Impulsive buying is an unplanned purchase without prior intentions to buy a specific product. It is often driven by emotions like stress relief. Characteristics include spontaneity, lack of prior knowledge, and potential regret. Types include pure impulse, reminder impulse from marketing, and suggested impulse. Planned buying is rational with research, while impulsive buying is irrational and spontaneous. Factors influencing impulse buying include internal states like mood as well as external triggers from marketing, displays, and promotions in stores. Surveys found over half of purchases are impulsive, and Americans with high individuality are more prone to impulse buys. Retailers use tactics like multiple exits past displays to increase exposure and impulse triggers.
