I disagree about the USPS never losing packages.
Over the course of a month and a half I sold about 1200 jerseys/cards on eBay. They lost:
1 registered mail to Canada
1 Priority mail to Illinois
Pretty damn good success rate although the 1 registered was for a 600 dollar card and the priority to illinois was a 70 dollar jersey. Neither was returned to me (nor delivered as far as I know).
Paypal sided with the buyer on both accounts even though I had a tracking number showing the items had been sent out.
Thanks USPS!

FU Paypal :madr:
So it is 100% possible that during the Christmas season it got thrown into the lost packages abyss that exists in the larger Post Office Branches.
