I'm curious, how would one know if a package had been held at the US border? I'm assuming a letter would be sent out eventually, but I'm wondering how long a wait it'd be to know. I placed a priority mail order recently that would be crossing the border, and I'm getting a little antsy as both the expected delivery date and general delivery time from that location to others in my area passes me by.
And yes, I know I'm being overly paranoid.
