I’m sure this is a complicated area, but can I add that from a vendor perspective I currently have to but the volumetric weight into the item, not the item weight to get shipping to calculate correctly. It would be much better if the volumetric weight was calculated from the dimensions, so the item weight could reflect the actual weight of the item.
Along with this, it would be good if the vendor could add “padding” to the calculation to allow for packaging around the items.
