Actually, we pay shipping now in the US as well.
But some of the places you can order that ship straight from Nepal, you'll pay $40-50 shipping, and end up with a product that Yangdu would sell as a villager or blem, as their top of the line product. So, in the States, we look at maybe paying another $20-30 shipped for a much nicer piece.
Yangdu gets a deal having them ship a large shipment by freight, and she can divide the shipping cost among many pieces. When you only ship one, the customer has to eat the whole bill.
