Warranties are huge profit, thats why when you go anywhere (from staples to car dealers) they push them on you. Especially with all the loopholes that they dont end up paying for repairs anyhow.

One of my friends "sells" extended warranties for every warranty sold the dealer gets $100, and he gets $100. His warranties are like $899 to, but they adjust somewhat to what you are buying. He has like 2 dozen dealerships that carry his warranty, so if they only sell 5 cars a week (between them all) thats $500 in his pocket. He has the same deal through the same company for financing, the dealer gets $100, and he gets $100. So if you buy a warranty and finance through his company they each get $200.
