How long did it take to reach San Fran when it left HK?
It got to San Fran the next day. Depending on the time it leaves HK and arrives it may show 2 days whenever/if tracking updates, but that probably has more to do with time zone changes than real time. Some people have reported their packages got stuck in San Fran for a few days. It has to pass customs first, and you know how efficient our tax dollar hourly employees are. I've only seen that reported once or twice, so it's pretty rare.
Even though it seems like forever, it'll be here before you know it.
