I do. I have a small safe deposit box in my local branch for about $1 a year.

It's great if you want to store some documents. But don't expect _real_ security. It's guarded by a minimum-wage employee, and the keys are usually laughably insecure. Banks know this, so they cap their liability for the loss of the deposit box at around $1000.

So don't even think about storing gold bars there, like they do in movies.

There _are_ companies that provide safe storage for high-value items, but they are pretty exotic.
