If you look back at the original story in this thread, the person who got the shipment by Fed Ex then attempted to return the animal by Fed Ex.
There is no way that person has the certification Fed Ex requires for breeders to ship to retailers. However, because that's how he got his chameleon, that's how he attempted to return it.
You can say it's the same, but this story proves it is not. Had the animal been shipped by UPS, properly labeled as a live, non-harmful reptile, it would most likely have been returned the same way and, hopefully, would have made it back to the breeder.
