When can I expect my package? It hasn't updated in a few days. And I've never order something from an oversees shipper so I'm not sure how long it should take.
(I'm not sure if the size matters but I ordered an iPhone case)

Just be patient. Tracking is… Mostly public relations. Do not expect it to be infallible. Just because there are no tracking updates does not mean your package is lost. The tracking info that is supplied to the consumer is not necessarily totally up to date vs. The carrier's own database. The consumer version of tracking will say "in transit" whereas the internal version can give you a given truck's license plate.

Your package is a container full of other stuff. If customs finds one fishy thing in a container, they may go through everything else in the container and hold up the given container for a week. It's not the carrier's fault if customs is fussy. Just have faith that sooner or later you will get it.

It should just take a few more days and it should be updated pretty soon. I've ordered tons of Anime, Lolita, Posters, etc. From overseas through amazon with normal shipping and they've never taken more than three days to two weeks. Although some are different you should expect your package no later then that ^^ time frame.
