Remember, the cost of post/freight IS included in the value of the item....ie...parts cost $950 and the post is $85 YOU will get charged GST as the total value is now $1035......they also add a few extra charges on top....paper work etc, and dont be caught out posting in 2 separate boxes because if they arrive on the same day at customs YOU will be charged if the totals are over $1000....been there, done that.....safest way when the value is over a grand is to get them to post them at least a week apart.
