ProjectorPoint (they used to eb a forum sponsor, but I do not see their link up there any more) ships via UPS. The UPS delivery folk are on a tight schedule and the delivery man did not want to stick around for the box to be opened, but he said if there is any problem to let them know and they will come pick it back up. For a big company like UPS it sounded like a very matter of fact policy they have.
Some companies ship through very small privately owned delivery services, which may amount to some guy who owns a truck and he might be personally responsible for paying for any damage to the goods he delivers. In this case, you can be sure the delivery man will be paranoid about damage, and he might also be unwilling to pay for any damage, since it will hurt him financially.
When you shop for plasmas, be sure to inquire about the shipper they use, since it can make a huge difference in how they handle delivery problems.
