Probably not. Merchants encourage consumers to buy extended warranties (also called service contracts) when buying autos, appliances, or electronic items because these warranties are a source of big profits for stores, which pocket up to 50% of the amount you pay.
Rarely will you have the chance to exercise your rights under an extended warranty. Name-brand electronic equipment and appliances usually don't break down during the first few years (and if they do, they're covered by the original warranty), and often have a life span well beyond the length of the extended warranty.
