List and describe the three types of consumer buying situations

What will be an ideal response?

1. Habitual buying decisions usually require very little consumer involvement and brand differences are usually insignificant. Typical for frequently purchased, lost-cost items (e.g., shampoo).
2. Variety-seeking buying decisions are characterized by low customer involvement, but important perceived brand differences. Brand switching is not uncommon because buyers can be influenced by advertising appeals, coupons, or lower prices to try a new brand. Brand switching is usually motivated by the desire for variety rather than dissatisfaction.
3. Complex buying decisions are characterized by a high degree of involvement by the consumer. Consumers are likely to be involved when the product is expensive, purchased infrequently, and highly self-expressive.
