Ebay dilemma...HELP!

If I remember correctly USPS only insures up to $100 if it's shipped Priority Mail. Insurance is cheap and depending on the item I automatically add it into the shipping cost whether the buyer wants it or not. It's assurance on your part. I normally do it on expensive items or stuff that could be easily damaged. So far its worked out for me. If your feedback right now is 100% then I wouldn't really worry about it even if he does leave a negative after a refund. You should be in a high 90's anyway. Nowadays people leave negatives for stupid stuff. IMHO unless he provides proof that it was damaged when he received it he is SOL. I don't think the USPS will do anything because no insurance was purchased. Did he have to sign for it when it was received? If so why didn't he inspect it then? Also USPS delivered it to his door? I know depending on size and weight you have you to go the USPS and pick it up.
