The month of December is usually the busiest month of the year for mail. Huge volumes are sent and received during the Christmas and New Year season.
The year 2010 was seemingly one of the worst ever, at least from where I am sitting it was....and still is !

In the UK, the sale of greetings cards was way down as people turned to ecards and email. It may have been a similar story elsewhere too.
From the UK alone, I am still awaiting the arrival of [at least] 13 items of mail...all posted BEFORE Christmas. At least 4 of the items were posted between 4th-10th of December.
Two of the items are quite expensive Philatelic packets, one less expensive, 5 Birthday Greetings cards and the rest Christmas greetings cards. And they are the ones I know about!

It is not only from the UK. I have friends here in our village from Denmark and France and they are still waiting for their Christmas Greetings and gifts from friends and family.
From December 19th, I have only received four items of mail, two from Canada and two from the USA. One was uncancelled, one got the dreaded Marker Monkey and one was destroyed...well, almost.
Items of mail that I sent from here have been arriving, but not all.
But is it the time to worry ?
In the UK, there were holidays for 4 days at Christmas and New Year for Postal workers. That's over a week in total. Plus, the airports were closed for some time during the bad weather. When I phoned them to make a general enquiry, I was told that mail to Europe and beyond did not move from December 19th until after Christmas. But due to the extended holiday, the mails moved much later...and then stopped again for the New Year. I was advised that it may be Mid-January before the backlog is cleared.
So should I worry ?
Has anyone else experienced the slowing of the mails ?
I am a little concerned that I have been singled out again because I am a collector of Stamps. This has happened before on two occasions.
I'd be interested to hear if all your mail has arrived, or if it is much slower from some destinations than others.
Thanks
