What to do if USPS says package is delivered, but did not get package?

The only advice I can offer is to pay for signature confirmation when dealing with high-value packages. It costs another buck or two, but ensures that the package won't get dropped off without you there to sign for it.

Sometimes PO's with lazy carriers scan packages as delivered when they get them into the PO. You might still get it.
