I deal with Ada post office all the time they have a great staff and are very helpful in every way. So its just must be me when I hear bad reviews Go with Priority mail it comes with insurance up to $50. And tracking if you don't like the price deliver it yourself and compare the cost. If you get a letter in your mail box that's not address to you simply put back in your mailbox and lift the flag.
