How to handle this problem with seller? Item was never delivered.

[Jack D.]

Checking the USPS site FAQ on Insurance claims http://faq.usps.com/ Submitting Domestic Insurance Claims Online -> claim requirements -> Section 3 shows this:

o For Items that have not arrived and appear to be Lost in the Mail:

§ Mailer must provide proof of loss for unnumbered Insured Mail only. Proof of loss is not required for numbered Insured Mail, Registered Mail, COD, or Express Mail claims. The mailer must present written and signed documentation from the recipient (such as a letter) dated at least 21 days from the date of mailing, stating the recipient did not receive the article.

So IF the item were insured they MAY have paid the claim. I would think that the $2 for insuring the package would be a lot less painful than the chance of dealing with what you're going through here and I would just include it in the shipping cost as my own piece of mind.
