Shopify Markets - Selling Internationally Just Got Easier

That’s great and what I am doing as my art collectors are global. However, how do you determine shipping cost without knowing how much final order will actually look like. I can put items of 0-1.5 kg at a certain price, then 1.5-3 kg cost depending on country but shipping fees are also variant on tube or large box etc. . Shopify offers an upgraded plan with courier companies calculations upon individual purchases but my NZ postal courier service which is way cheaper isn’t offered as an option.
