Extended warranties are like a casino:
* some who play will win
* a very very few will win very big
* most by far will lose
* the casino will make a lot of money.
Only the casino odds are so much better...there the percent returned to the player is generally more than 80% as opposed to the extended warranty where it approaches 20-30%. Like a casino, you hear the stories of the people who win big and that persuades you to play. You mostly don't hear about all the many, many more people who lose.
