Hey so check this thread out. The option for my school expedited shipping was fedex and fedex doesn't deliver to PO boxes so hope you sent it to the correct address. As a comparison, I sent mine through normal mail and it was received 5/28 and they sent me the email confirmation yesterday. Hope everything goes well. http://forums.studentdoctor.net/threads/fedex-transcript-to-amcas.1008646/
