ok, so i won some tickets to a game and the seller sent them on nov. 2 priority mail with delivery confirmation. they didn't insure it but we thought that is would arrive in plenty of time since the game is today. well, the mail already came and there is still no tickets. is there anything that can be done? i mean will usps reimburse one of us the amount since the tickets can't be returned? priority mail typically says 2-3 days so i don't know if both the seller and i are out the money. help...
