@maporsche,
I looked. They offered an iphone warranty for $99.xx covering your phone for two years, up to $299.xx. Also available with a monthly payment option. Really? One hundred dollars to cover three hundred dollars, and the manufactor probably includes the first year as part of the price.
I've been offered these third party warranties on stuff costing less than $50.00. If it were free, I'm not sure it would be worth the hassle of securing enforcement. On major appliances, the cost is almost always equal to the cost of one major repair, which you are not likely to need anyway.
In other words, you could say I'm negative on the concept.
