paying for USPS fault

[rp12367]

I just had a problem today. Won a card off e-bay, seller shipped, gave tracking number. USPS said card was out for delivery on Saturday 9/1. Card never was delivered, status was still out for delivery until yesterday, last night status said, rerouted for international delivery, whatever that means, also showed 9/1 as date even thought it was 9/3. Then all of a sudden today USPS said card delivered 9/1 and international thing is just gone. Today 9/4 no card, talked to mail lady this afternoon (who is a temp for past 3 days, regular mailman on vacation) says she hasn't seen it and maybe it will turn up. Im going to post office tomorrow to talk to them, but I'm sure I will get a run around. As far as e-bay and seller are concerned it shows I got it so I guess I'm outta luck. Hopefully if it got delivered to wrong address the people are honest and put back in mailstream. I wouldn't expect seller to make good on it, it was post office screw up, and even if it was insured USPS says it got to me.
