I just learned from Bitsyncom that tracking numbers aren't generated until they leave mainland China [i.e. Customs]. Then it is handed off to DHL which then generates the tracking number.
can we infer that jeff's package has not left china, but bitsyncom still expects delivery around thursday? i guess it's possible. if thursday delivery, then jeff should have a tracking number by tomorrow at the latest.
I failed to ask Yifu the weight of each Avalon device. (To figure out why the paid so much for Jeffs delivery)
$400 is a pretty hefty sum of money. I suppose they must have paid extra to ensure extra quick delivery. The only way to know for sure is by posing the question to him.
Best guess, Chinas customs office is being a pain.
