Can I negotiate the prices I see on Maersk Go?  Can I change the vessel my shipment is on? Can I change the origin (COO) of part of my cargo? Can I extend demurrage or port storage freetime? Can I change the origin (COO) of my shipment? Can I change the destination (COD) of my cargo? Can I extend export freetime? Who can I contact if I need support for Maersk Go? What happens if I cancel my shipment? What happens if Maersk cancels my shipment? If I select Rollable how many times will my cargo get rolled? Why is Maersk making these changes to Maersk Go?
