Absolutely the safest way to ship short of you picking it up yourself. This piece ships to the contiguous United States for a flat rate of $380, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
