Problem with the USPS is that they only deliver in the US.
How late is the package?
Might it just be clearing customs or hung up there. I've had packages cross borders before and it will say delivered when handed over to the other country, even though it has just entered the other country's post system. Past that point it may be held up for other reasons like customs. It might even be a random customs checking of packages. They don't check every one, but every now and then I will get a package from abroad and have to pay additional customs, even though I have ordered several times from the same vendor with it never happening before. One time when I ordered something from Canada from Pierre, it took a couple weeks after it being delivered to the USPS. When I ordered from tosho knife arts in Canada, however, it took 2 days after being handed over to the USPS. It can really vary quite a bit.

As I recall, when I ordered Pierre's Suji from Lefty, it spent a lovely 4-5 day vacation in the Chicago postal center before heading out to me.
I believe this is a plant by the UPS or FedEx to bring dangerous propaganda to the U.S Postal Service. A fine company that is as old as this fine country that has served it's countrymen very well. Who is this really? D. Scott Davis? Frederick W. Smith? CONFESS VILE PRIVATE COMPANY DEMON CONFESS!!!!!!

See? This is why I never trust Canada..... Especially Denis Dyack and the Silicon Knights.
