Ditto the above.
A specific localized bit of damage well inside the case may raise some questions as opposed to the damage being from the case inwards.
As HK said, the shipper insures.
As well (and I have a thread on this in the Open Mic re. my own guitar) be aware that in most cases when you sign for the delivery of a guitar, you are ALSO signing, declaring, the guitar arrived undamaged. You'll need a very kind, and generous insurer to look beyond that.
Good luck.
