You're right. I called the company to find out more about it. I guess since they're new they still have to work on getting coverage in every state. They said they plan to have Texas covered by the end of the year.
A safe deposit box might be a good idea. And if you're worried about your valuables you can always insure them. I was looking into it for my valuables and found this cool website that was pretty helpful. www.safedepositboxinsurance.com
I just looked at a website for an insurance product that just insures safe deposit box contents. I do not think you tell them anything about what is in the box. just pick the value or amount of coverage and pay the premium. It doesn't seem like it is available everywhere but it might be worth checking out. www.safedepositboxinsurance.com
