Hi,
Currently, the shipping component for Hikashop has a "volume" and "weight" criteria to include or exclude products, but that does not work for the majority of shippers, who have their criteria set by length, breadth and width.
If any one of those figures does not match the criteria set by the shipper, their API will automatically assign another shipping method and price.
However, since your system only has "volume," it's not possible to set those individual criteria, which means you have to do it manually.
Can you please change this so that it can be set up according to shipper criteria? As you know, volume can be the same with limitless combinations of individual dimensions, so this really doesn't work for this purpose.
