3 out of 3 failures. Never again. I'll pay for UPS before I ever use the US Post Office again. I sent certified mail with tracking numbers. One was delivered to the wrong state, the other two ended up in limbo. They have never been delivered and if the post office screws up its all on me to resolve their mistakes. Call their 800 number and wait on hold forever file a missing mail claim. How do they stay in business with this level of crappy service
