I have the same issue in New Zealand. Trojans are about twice the U.S. price here. To ship HAZMAT items by airfreight requires that they not be included on passenger planes. Price goes up and airfreight for batteries would be prohibitive due to weight regardless of HAZMAT status. Transportation by ship would cost close to $1000 U.S. No savings over buying six T105's here.
P.S. Rolls are the Cadillac of batteries. (no pun intended)
