In Canada, the chirstmas rush has started, or at least that's the excuse I get... There are little flyers at the post office with destinations and dates, considered the "cut off" dates for your package arriving in time for xmas. Cut off dates for certain continents start in mid-Nov and the last date, (air mail to the USA from Canada) is Dec. 9th, I believe.
I'll see if I can find that flyer...
