How does the concept of complementary goods impact consumer behavior and purchasing decisions?

Complementary goods are products that are used together, such as peanut butter and jelly. When one of these goods is purchased, it often leads to the purchase of the other. This impacts consumer behavior by influencing their purchasing decisions. For example, if a consumer buys a gaming console, they are likely to also purchase Video Games to go along with it. This concept can lead to increased sales and revenue for businesses that offer complementary goods.
