Consumer services refer to the formulation, testing, consulting and analysis of many consumer products like food, cosmetics, household items, and construction materials. Consumer services also include goods, services and obligations primarily for personal use like food, drugs and devices. There are different types of consumer services such as beauty, transportation, communication and appliance installation. A key difference between products and services is that products can be touched while services involve actions performed by people and cannot be touched or resold. To be a wise consumer, research options thoroughly, find discounts, compare multiple providers, review receipts carefully and refuse unnecessary personal information requests.
