The tracking info for my order from ImportCDs says that my copy of Bitches "Departed Shipping Partner Facility" on August 16, but that "USPS [is] Awaiting Item" two days later. The "shipping partner"? DHL--which in my experience is awful about providing reliable tracking.
That's the way a lot of these major outlets do it these days...sometimes multiple carriers before it reaches the Postal Service...and until it reaches the USPS the tracking is "cloaked"...like a Klingon Bird Of Prey...and I hate those Klingons
