This is not good; I've used them in the past with no issues but something's gone wrong here. All that aside, USPS tracking is a joke IMO; the shipment never shows locations and I've had things delivered and shown as still in transit, and vice versa. UPS or FedEX, please. If they won't respond, contact their local (Seattle?) BBB or get SMART to go over there with a baseball bat*.
*just kidding, of course!
