Hi,
the product weight is 0.100 Kilograms, the free shipping limit is 0.05 Kilograms.
I have disabled the OPC, the problem is still there.
If I order 15 logo (weight 0.100 Kilograms) VM calculate the final weight Unità di misura : 0.0015 Chilogrammi
So the VM apply correctly the free shipping, but the correct weight should be 1.500 Kilograms
