My worry is that Sideshow will try and keep shipping costs down (they're calculated volumetrically) by skimping on the protective packaging required to get these items to us in undamaged condition e.g. oversize boxes, foam corner protectors, etc.
I actually very much doubt that, since it's my understanding that anything which arrives damaged, is replaced or fully refunded (including any new shipping costs) at Sideshows expense. Now sure, they may then have insurance 'options' to recover some of that expense, but either way, to much damage is only going to be a bad thing for Sideshow.
The worse case for the customer, is that they don't get the item they wanted, sure to piss them off, but never going to cost them a cent in the end.
