Shipping rates will only be given once the product is ready to ship or almost ready to ship. Boxes & foams are manufactured only during the final stages of production. Its safe to assume that 1 box will most likely cost around 200-400 USD each, and if a statue is very big theres a high possibility that it will come in 2 or even more boxes. Museum type statues will most likely cost less simply because they require less space.
Ready to ship items already have their shipping rates ready. So you will need to pay the shipping cost together with the price of the product.
