We shipped several mounts to Hawaii via DHL. A 110 pound oversized crate was $267 going 2nd day air. I could not find anyone, including Yellow Freight, who would give us a better deal. Yellow Freight wanted $400 and it would have taken nearly a month by boat. UPS asked for $800. You might want to call DHL and see what they say (1-800-CALL-DHL).
