OP - I have made purchases or had equipment delivered without insurance and have never had trouble. I would go ahead with the "missing mail" report. I would find out from the seller the size and appearance of the package. I have heard of people having success doing this and sincerely hope you will be one of them!
Alll the best!
PS Check with the seller to be sure he had your address information exactly right. That's a big deal. If he did possibly mess up you could include the information about the possible mailing mistake to the PO to help the USPS hunt down your package.
