If it is the plan I think it is, it's a third party insurance policy issued by a (probably) distant company. Get a hold of a copy and read the fine print....very carefully. You will probably find a bunch of exclusions and escape clauses that are not to your benefit.

Be wary of clauses that basically limit your benefit to the current value of the appliance, or to a replacement of their choice with a unit of similar value to what you have. If your appliances are more than a couple years old, their value according to such a policy may be close to zero.
