Funny you would say that, Uniserver. When I used insure packages, I would insure it for double it's worth. And it would go through with care. But with no insurance, they would use it as a soccer ball they have at their man distribution site! The reason is, they do not want to pay for damage done.
I remember sending glass figurine to an ex years ago. The figurine was about 4in tall X 2in X 2in. I wrapped in newspaper and then in flexi foam (thin foam sheets that can bend without breaking) and then in packing peanuts in a box bigger than a shoe box. Took it to USPS, and told the postal-lady that it was fragile. She took out her "FRAGILE" Stamp (6in across) and banged each side of the box with it! She basically destroyed that little figurine then and there.
With Macs, I've been very lucky. All survived the trip but all the boxes look like they went through trench warfare before arriving to my home. One box I received a 1400 in looks like Cookie Monster took a huge bite out of the side corner! I should have taken a photo of it before throwing out the box.
