That sucks. I'm sorry. I orderd a $100 kindle fire one time and it never appeared on the doorstep. The post office manager kept saying he would take care of it, and we filed three claims, but apparently they marked the package as "delivered" so they took no responsibiliy for it. Theft is not that common out here, but we constantly get other people's packages. I am almost positive that the postal person delivered it to the wrong house, scanned it, and whoever got it decided to open and keep it. Nothing ever came of it, and ebay wouldn't honor the money back guarantee because I purchased it under "guest" paypal user (stupid me). We did raise such a huge stink about it at the post office, however, because now the postal person is careful to hide the package behind our planters for us.
I hope that ebay can refund your money at least. Don't let it ruin your holiday, though! Remember, there is always yule log cake!
