Ordinary mail, postcards, packages, and all other stuff that gets send by mail companies: the delay was huge this time. (in the Netherlands at least) My friend send me a package with a charger in it, without being too big (bubble-wrap envelope).
When he send it, it took 3 weeks to arrive. Christmas cards didn’t arrive that fast either: this took 1 week. I live in a city, and the post office is very close to me. Even when cards got send from within a 10 miles (approx. 15KM) radius, it took a very long time to arrive at my home address.
PostNL, the company that handles the mail in the Netherlands, did not want to give any explanation of the issue. They only told me that I didn’t live in a good location to receive letters and postcards fast. They also told me it would be better next (this) year, and “happy holidays, thank you, goodbye”. I certainly hope so, since I don’t have time for reading Christmas cards in February.
