The US Postal Service VS Canada Post !!!

The christmas parcels were shipped and arrived safely at both households. My parcel from my folks in Iowa arrived yesterday all intact and no damage. US Customs didn't open it this year so thats really good of them. Mom mailed her parcel off on Dec 6th and it arrived here yesterday ( dec 19th ). Not bad for a parcel for the USA, 10days. On the flip side I shipped mine down there to Iowa on dec 14th and it arrived today (Dec 20th). 6 days later, and yet once again US Customs didn't open the parcel. It makes one wonder why it is that when I send something to the USA it only took 6 days and why it took almost 2 weeks to go from Canada to the USA. Wierd isn't it, but by the same token it only takes 3 days to go from where my parents live in Saskatoon, Saskatchewan to here in Calgary, Alberta a mere 386 miles away and where sis lives, Maquoketa, Ia is 1534 miles away. Time to find out how long it takes to goto Europe !!!!!!
