     In this case, we should query the Australia Post API as per normal.
     
     
     3.
     Cart consists of one or more "disregard shipping" product(s), and one or more other products that attract shipping charges.
     
     In this case, we should query the Aus Post API, only taking into account the product(s) that attract shipping charges.
