With any (domestic, international) shipment I've dealt with, sender is the one who has to raise a fuss about delivery problems, even it claims they left it at the front door/garage/back porch/trash can/someone else's house. Or when it gets stuck at a USPS ISC terminal into/out USA.
100 games = bulk cargo weight? Not sure how that routes around.
I'm sure byuu has heard of all this by now, so doesn't mean much.
