Complementary goods are products that are typically used together, such as peanut butter and jelly, or salt and pepper. When used together, they create a greater effect than when used separately. For example, if someone is trying to lose weight, they might eat a salad for lunch with light dressing and no croutons. However, if they add a tablespoon of olive oil to their salad, they are getting more healthy fats and calories, which could help them lose weight.
In conclusion, complementary goods are items that are used together to create a desired effect. They can be found in a variety of industries, and can be used to increase efficiency or to provide a more complete experience for the customer. By understanding what complementary goods are and how they can be used, businesses can improve their bottom line and create a better customer experience.
