Total dimensions and weight calculation
If
total_actual_weightis provided, it will prevail over the items' individual weights. It not provided, then the items' weights are mandatory and will be used to calculate the total package dimensions.
Likewise, if theboxobject is provided, then its dimensions will prevail over all individual items' dimensions and will be used to calculate the shipping rates. However, if the total box isn't provided, our algorithm will compute the best box based on the items' dimensions, which will then be mandatory.
