They are the Chinese Tak dealers. They will not do mail order because that would violate distribution deals, however can be significantly cheaper to fly to Hong Kong, pick up a Tak and fly back with it as baggage than to buy a Tak in Australia, even when you include the air fares!!! Know people who have done it......wish I had the money to do it!
