OWW1 maintains locking mailboxes located on S. Century Drive, between Gross Drive and Big River Drive. The cost of a mailbox is $50, with all fees going into a mailbox repair/replacement account. Half of the fee—$25—is refundable, upon termination of mailbox use and surrendering of the key. In the event of a key loss, a replacement will be provided for a $5 fee. You can order a mailbox online here.
