Not quite. I have had to use the Concierge for warranty issues for a PC and a camera. In both cases, where the Concierge went through the various troubleshooting steps (lengthy with the PC), and it didn't work, they forwarded me to the second tier support at the manufacturer, with whom they discussed the issue before the manufacturer took the call, and the manufacturer arranged for pickup of the product to be repaired.
Anyways, Concierge support is free with the purchase. I have never bought the extended warranty, but I do know that they are an "all perils" warranty (at least for the PC and TV). If I was to buy an appliance, I would likely pay for it.
