When you make a purchase, you want to know that you're covered in case something goes wrong. That's where warranties come in. A warranty is a guarantee from the manufacturer that the product will be free from defects for a certain period of time.
Most products come with some kind of warranty, but the coverage can vary widely. For example, electronic devices may only be covered for 90 days, while major appliances are often covered for one year or more. And while some warranties cover repair or replacement costs, others may only cover the cost of parts and labor.
So when you're considering a purchase, be sure to find out what kind of warranty comes with it. That way, you'll know what to expect if something does go wrong.
