Mine neither. Usually USPS is pretty good at updating the tracking. Strange.
Well, each time I've bought stuff off eBay US or SF and have used USPS, tracking has been updated extremely quickly... Maybe I've just been lucky? I must admit though that my experience with USPS is very limited - maybe something like only five shipments all in all.
Same here. Almost one week now (!) since I received notice that the package had been shipped, but still no tracking update.
