With continued thermal cycling, patching porcelain is a big iffy subject. The crack is likely to grow over time. When this sort of stuff is shipped to the vendor, it is usually in a full pallet. When a single one is shipped, there's nothing other than the box to protect it, and the box was not designed for shipment as a single item. This is pretty much true for any brand. Some vendors put the things in a larger box and foam it in place...those have a chance of arriving intact. It's always safer to find a local vendor. Good luck.
