Might as well reply to myself to update this... Finally got an answer from the post office. Basically it was "It must have been delivered to the wrong house but the carrier doesn't remember where it might have gone. Nothing we can do unless someone turns it back in us."
Called back to the shipper and got much better news. Mad props to Apollo for this... they're replacing my shipment and sending it out tomorrow. No reason I should expect them to do this (they even said they don't often do this) since they don't have proof that I didn't just take the first one and run with it but I'd call this above and beyond as far as service goes. Should be shipping out tomorrow and I'll see it in a couple days.
