Ok I talked to transhipper Linda Olson...she said you want to avoid labeling the box as live fish on Express shipments:
FedEx is actually in charge of USPS Express...meaning that they are controlling the shipping for their biggest rival. Since FedEx dosen't accept fish they just push the box aside...this would explain my problems with getting boxes labeled LIVE FISH. Not only that but I was digging and found out that FedEx is to blame for several DOAs because they did not even attempt delivery or they were sent back to the main hub. If you are shipping FedEx or USPS Express NEVER label the box as Live Fish.
Hope this dosen't offend anyone who works for FedEx...just reporting what I've read.
I will NOT be labeling my boxes as anything other than HOLD FOR PICK UP!
