Require a direct signature at delivery. I require a signature so that I have proof that the animal did arrive and at what time.. it keeps people from getting the snake and leaving it in their car at work thus killing it and claiming the animal arrived this way.. If you sign for the snake at 8:30 am and call me at 8 PM saying the animal is dead we have a huge problem..
Require a direct signature from the addressee, and you'll cut down on the chance at being scammed..
