All US orders have flat rate shipping fees based on how much is purchased. Orders for any country other than US are calculated by the USPS postal system by weight. Your order's total weight is calculated and then the shipping service that must be used is synced with the live rates utilized by the USPS. If your order costs a lot to ship and you're from outside the US, it's probably because it weighs more than the threshold weight for First Class International Shipping and is bumped up to Priority International weight which is substantially more. Only smaller orders will qualify for First Class International which is the cheapest rate we can get.
