I look at it like this.
Warranties are really "insurance policies".
I'm a bit of a risk taker for a reason. Warranty companies (like insurance) make money. They have to pay for buildings, employees, record keeping, computers, pencils, phone, A/C & heat bills... etc. In other words they may WAY more money than they pay out.
So basically if you consider all that overhead people have to be PAYING IN way more than they are paying out.
So I'd take any premium/payment that you are considering buying a warranty with, and stick it on the side for a rainy day WHEN something breaks. This includes house and truck.
Sure there are exceptions to this rule, but in general, I don't find warranties worth it.
Just my opinion.
