when shipping subs, I always want pics of the sub before it leaves and Fragile, Heavy, and label which side is up. That way if a box shows up on my or the buyers doorstep damaged or SIDEWAYS, I have a much better chance of getting my insurance money back.
Then there is the NO NEWSPAPER OR PEANUTS issue. Newspaper 'packing' will void the claim as the shipping companies have packing guidelines listed.
