RE: O'Brien Hobby experience
Sounds like it's the time and place for the hobby shop to lay out "the rest of the story" I have a feeling that if the USPS was indeed the cause of all the problems and what will likely be substantial lost business to the hobby shop due to bad press, the post office may ante up and admit to the errors in order to avoid potential litigation. Mailing "first class" is a guarantee of accurate delivery.
The doors open, someone only needs to walk through.
