Case of the Missing T-shirts: SOLVED!

If you haven't read THIS POST yet, you need to start there.

If you have already done so, then proceed.

As you will remember I sent some T-shirts to my sister-in-law on August 24.  She never got them.  I followed them via their customs tracking number, as they made their rounds of the United States.

THE UPDATE:
Since I posted, the USPS stopped updating the tracking.  I actually had to send a request that the tracking continue to be seen.  So here's what I saw.

Warren PA (where we live) 
Jamaica NY
Bethpage NY
back to Jamaica NY
Brooklyn NY
back to Jamaica NY
Warrendale PA (which is down near Pittsburgh.....I was hoping it was getting returned to us here)
Chicago sort facility #1
Chicago sort facility #2
Chicago sort facility #3
back to Warrendale PA (again hoping it was being returned to us)
back to Chicago sort facility #1
back to Chicago sort facility #3
back to Chicago sort facility #1
back to Warrendale (outside Pittsburgh) facility for the 3rd time.  (THIS is where I last updated the trip)
back to Chicago sort facility #1
back to Chicago sort facility #2
back to Chicago sort facility #1
finally back to Warrendale (outside Pittsburgh)

It seemed as if it was just stuck in Warrendale.  No movement for a few weeks.

So yesterday what should be in my mailbox?  THE PACKAGE!!!!!!!

OK I will take ownership that I didn't address the package correctly.  I screwed it up.  I addressed it on what I was given and that wasn't right.  So it was destined for struggles. 

HOWEVER.....why did it have to take the trip it took?  The USPS recognized that the postal code wasn't right.  But my return address was.  Why did it have to go to all those sort facilities before they returned it?  Why did it take 2 1/2 months?  Why didn't they send it across the border and let Canada Post sort it out? 

Regardless.....I have the shirts back in my possession.  There was a small rip in the padded envelope, but the T-shirts were fine as were the cards that we sent with them.  Actually they're still both nicely pressed.  I now have to extra shirts to sell.  Anyone want them?  I'll tell you what....if you're reading this and you want to redeem those two shirts, I'll drop their price to 18 local or 21 shipped (just for those two shirts).  HA HA

I have blurred out the postal code so as not to incriminate myself.
