I have some stuff coming from the US via USPS.
USPS packages tend to be dealt with by Canada Post.
I have been tracking a couple packages and they all say:
"Attempted Delivery Abroad, June 27, 2011, 8:00 am, CANADA
We attempted to deliver your item in CANADA at 8:00 am on June 27, 2011."
What does this mean? Will the packages be sent back to the US? I hope not...
