My wife recently had an item sent to her and it arrived damaged.
She went to the post office to file a claim and found out the following.
- You have to give the post office the broken / damaged item.
- Proof that the item was packaged correctly. Ie the origional packaging
- The only way you can get the original item back is to bid on it IF it shows up on their website where they sell lost or damaged items they paid a claim on.
As for the Game Board box...
USPS Discontinues Priority Mail Flat Rate Large Board Game Box
States that the box was intended for the board game industry.
As for shipping an intake manifold in a board game box... IMHO you are looking for trouble. You need 3 inches from the item to the outside of the box in all directions for propper padding.
The intake is heavy, has sharp edges, and I have seen too many heavy items sticking out of their shipping box both from businesses and from online sellers.
