Many credit cards offer to extend the general manufacturer's warranty, in some cases up to one additional year. Manufacturers often guarantee their product for 12 months, but if you buy with the right card, you might be able to extend this to two years or more. Discover and American Express offer excellent extended warranty coverage. Ask which of their cards emphasize this reward and make sure it applies to products you typically purchase.
