I don't know if there was 1 undercover or 2. But I know for 100% fact that they did wait at the post office. 99% of the time you will be OK, and it will be fine. But they DO wait at the post office. and they DO do controlled delivers waiting for you to pick up your package. I can 100% confirm that. I am not trying to scare monger here. I'm sure they wont do it for personal amounts, but it has definitely been done before.
