Already paid for itself several times over

I've had LifeLock for about 2 years. I got it after being caught up in the Target data theft. At least 3 times LifeLock has notified me of people trying to open accounts in my name. No idea how I would have known if LifeLock didn't alert me, at least not until damage would have been done. Just today I got another alert about a service being opened using my social. LifeLock called the vendor, discovered it was indeed fraudulent, and the vendor removed the service and had the credit inquiry removed from my credit report! This service has paid for itself many times over, especially since we're looking to buy a house soon and need our credit in good standing.
