Probably a dumb question, but is the tracking number giving you any useful information?
Mail certainly arrives at my apartment complex (in Danshui) on normal Saturdays. Not sure if it’d be the same for packages. But this weekend’s a bit weird because of the Thursday & Friday holidays - is this Saturday a typical Saturday, or another holiday?
Based on the link @tando gave above, FedEx won’t be delivering tomorrow - but is the package with FedEx, or something else?
You can’t do black cat if it’s coming from the states…
Only time I have stuff come in through a Taiwanese delivery company (Xingchu transport, black cat, etc.) is when ordering stuff from Taobao and selecting sea shipping. It gets handed over to a Taiwanese shipping company for door to door delivery.
