There are two main ways to calculate shipping rates in the shipping world. These are flat rates and dynamic rates. We use flat rates. Different countries are combined into zones, and the shipping rate doesn't change within a zone. For example, Italy, France, and Germany are all in the European Union, so shipping to them will cost you the same.
Also, the shipping pricing can sometimes change due to courier changes, policy updates, customs/tax regulations, and other reasons. We continuously update our partners with the latest information.
Of course, the final shipping price depends on the product, its size, and how many products are in the order - you will see the final shipping price when fulfilling your order in our fulfillment system.
