To Stockholm, Sweden, it almost always takes precisely one week, unless it has got stuck in customs or it has been sent during the holidays when the mail services has had too many shipments to handle at once.
This has been the case for over a dozen (possibly two dozen) small packages that I have received in the last decade, both cheap letterpost and international priority.
However, a few have been lost in transit -- and these have all been small padded envelopes sent without insurance. Nowadays, I usually ask a US seller to ship in a small box, just to be sure.
