Funny that you should mention that - I liven in FL. I bought some slabs from Dre, and the post office sent them to Puerto Rico. When I called the PO to see why, more than one rep said (and this is a close-as-I can-remember literal quote), "I cannot understand the the flow of mail, and cannot say it is not normal for your mail to go to Puerto Rico before going to FL"
One thing I will give to the USPS - they lost/damaged a few of my packages over the past year and were really quick in paying out. Much faster than FedEx, who actually denied my last claim.
