I think if you use tracking and insurance you should be fine. The post office doesn't always update their tracking until the package has already been delivered but I've heard that they are better at paying out insurance claims for lost items than UPS. I won't be using UPS anymore because when I shipped my last package they just handed the package to someone without getting a signature and another time they just left it on a doorstep. I like USPS Priority with delivery confirmation and insurance.
