I used it for mp3 speakers. Didn't need to send it in. Was less than $20, though. On a SPG card.
I used damage protection (is that what it's called) for a camera that dropped. They just sent me a check, without having to return the item. Camera was about $140. That was an AMEX Gold. I actually had sent it in to Canon, but they wanted to charge me to fix it, because it had "evidence of being dropped", so I just told them to forget it. Low and behold, I opened the package up, after letting it sit for a while, and it worked!
