Question: Hello, this is William Donohoe from The Shipping Shack, Inc. We can assist you with your shipping needs. 1st of all, you should go straight to Matson to ship your car. Everyone pays the same for port-to-port. This is regulated by the Jones Act passed by Congress back in the '70's. No one gets a discount shipping their vehicle between Hawaii & the mainland. Per Homeland Security, you are not allowed to place anything in the car. No exceptions. We can assist in shipping your personal and/or household goods. List them here on U-Ship. We will then submit a quote, mahalo. (5/11/2008)
