I wish I could show you guys the way we receive our packages. Picture a large plastic hamper, about 4' long, 3' wide, and 3' feet high. When it leaves the processing plant, it is filled with packages. It may contain 10-12 larger packages, or it may may contain 300-400 small packages, or it may contain a mixture of a couple of hundred large and small packages. If your package with the unprotected slab in a bubble mailer happens to be on the bottom of 300 small packages, with a dozen heavy packages on top, you may very well end up with a damaged slab.

The processing plant is sending hampers of packages to 150 or so different post offices, some of them are 100 miles from the plant, and the only efficient way to send them is in these large hampers. So, always package your item as if it will be on the bottom a hamper with 300 other parcels.
