Does your daughter live in a town with city carriers? I use to live in a small town without city carriers & my box rent was only $40 because I had no other option for mail delivery. The neighboring city has city delivery so if you want to rent a PO Box in order to get your mail earlier than when your carrier gets to your house (or for any other reason) there is a higher charge. That's because there's other delivery options available and a PO Box is kind of a luxury or convenience item.
