I had been debating getting this for a few years and finally got it just 2 months ago after going crazy not being able to locate my dd's ss card. I keep them altogether in a lock-box, but had to bring it with me to register her for Kindergarten. It was making me sick to my stomach thinking who could get ahold of it and the damage they could do to her. Also, I had been so careful with it, it was driving me crazy that I couldn't find it! Thankfully, I finally found it tucked into an envelope with her birth certificate.
As soon as I found it, I signed up for Zanders. I was trying to decide between Zanders and Life Lock, and went with Zanders because it's endorsed by Dave Ramsey, who I thoroughly respect and trust in these matters.
Unfortunately, no matter how careful we are, mistakes happen. A friend's husband had his ss# stolen and his identity stolen. When he tried to get a new ss#, he was told he couldn't have it done because doing that was for "emergencies only"!

What could be more of an emergency than having your identity stolen?! Another friend had her purse stolen at work, right out of her desk. Our mortgage company gave us a year's free of Identity Protection after having lost some back-up tapes containing everyone's personal information!!

There was a bank that was in trouble a couple years ago for throwing everyone's personal records (statements, cancelled checks, etc) in the dumpster right behind their building without shredding anything!!
For me, this insurance is now worth the price and headache if God forbid, anyone in my family had their identity stolen.
