Like you I have to look at freight costs. : I live just across the Tasman in the West Wimmera part of Victoria. :
Might I suggest you look at :-

For example - I recently purchased 10 leather jackets through my drop shipper. Weight 41 lb approx 18.6 kg. Their S&H from Texas to Mbex in California was $US34.07 or app $NZ42.26. I asked them to hold onto the consignment as I making more purchases. A couple of days later I purchased some R.C.Cars from Liq. Fullerton CA warehouse. Weight 75 lb or 34 kg. S&H from Fullerton CA to Mbex in La Habra CA was $US43.19 or app $NZ53.58. Mbex consolidated the total of 4 parcels into one shipment. FedEx give Mbex members a 30% discount. ie 116 lb app 52.7kg. Cost $US671.81 or app $NZ833.28. All up cost (cost of goods + S&H) = Coats $NZ49.55 each & R.C.Cars $NZ13.10 each. I have already sold 2 coats at double the cost (less eBay/PayPal exorbitant fees). I have only started to list the cars this evening. All up I have found Mbex & FedEx VG. Both sites allow you to track your shipment.
In addition to the above might I also suggest you use Link hidden: Login to view for your currency conversion rates. At least then you know your true cost in $NZ.
