The person who won the card can go to his local post office in Glendale and ask them to track it. I had a package from the Netherlands stuck some where in the system for two months. I had a Netherlands tracking number. Gave it to the clerk. She looks it up. Says it's in Boston. It shows up to me the next day. USPS is getting more weird by the day.
Once I ordered something (not cards) and the dealer accidentally got one letter wrong on my address; no bog deal, maybe? Nope, it sent my package to Cambodia! But the dealer was very, veery nice and re-sent a new order for free. Missed Christmas for my kids but they still got the gifts.
