Is there a way to stop shipping calculation via script? We only need to stop it for a small segment of our customers. We have a third party service receiving purchase orders. Then their integration creates Sales Orders in NetSuite. These customers are using their own shipping account but when these orders come in, the shipping rate has been calculated and added to the total. Any ideas? Definitely thinking I need some user event script... Thanks,

usually you only need to set the shipping cost

shipping cost overridden field sounds interesting
