I purchased some books on Amazon and sent the package via USPS to a friend's address late December. I totally didn't follow up on it, and realized that the package was never delivered to my friend. So I checked the confirmation number, and the status says that it's "unclaimed." I couldn't find any information on what it means to be "unclaimed" on the website. Does this mean that the shipment will be returned to sender? Just sit in the warehouse 'til it's claimed? Destroyed?? Anybody know? BTW- the tracking # is: 9102049390094171212859 if you want to take a look.
