Keep in mind that it can take a while for a package to cross the pond and be delivered. The other way around I usually get packages from the United States within 10-14 days, but sometimes it takes longer - at the moment I'm still waiting for a set that was mailed on December 26...
I'm waiting for a package from Amazon UK that was shipped 2 weeks ago.
OTOH, I received a package from The Netherlands (from subdist.com) in a week.
This month a package containing books from Amazon UK (not third party) I ordered with Free Super Saver Delivery was actually lost in transit. A first for me. Of course they promptly send me a replacement with expedited shipping.
The lost package's last known location was Grimbergen, Belgium. I wonder if it'll ever arrive in The Netherlands and what it was doing in Belgium in the first place.
All European Amazon "Free Super Saver Delivery" packages destined for the Netherlands seem to go through Grimbergen, Belgium. I guess it's a TNT distribution centre. I am now waiting for the Miles Bootleg 2 set from Amazon Germany that's supposed to be delivered today (Saturday), but according to the tracking number it's still at Grimbergen, so there'll probably be no delivery until sometime next week.
