When people purchase products or services, they often want to know that their purchases will be worth their money. If an item breaks or malfunctions, or the service is substandard, people typically want the situation to be corrected. Consumers can be protected from such circumstances when they purchase a warranty. A warranty is often valid for a year or longer after a person has purchased an item. Warranties commonly are attached to electronics, such as televisions, music players, and more, as well as services such as roofing, carpeting, and other home improvement services. This guarantee promises that the good will be repaired or the money for the service will be refunded if the good breaks or the service provided is substandard. Without a warranty, people often are reluctant to spend money for such purposes. Once a warranty expires, people have the option to renew it in most cases if needed.
