I'm sure The laws changed since last year aswell. That extra time and paperwork is what I do for a living

Previously you had to pay if the total of duty and/or gst calculated was over $50. So if it was duty free, but worth $800, you had to pay $80 in GST.

Now though, it doesn't matter what is owing (tobacco and alcohol products excepted) so long as the total value of the goods is less than $1000.

However, say you bought a set of your preferred brand sway bars, suspension, and springs. Then you sent them all at the one time but in 3 different boxes to to try and make the value of each box under $1000. Customs can (and quite often do) pick up on this and could deem them to be all one consignment and make you pay up.

If you buy and ship them seperately then you are sweet. Just compare the additional shipping charge for doing three seperate orders (together might cost $30 total, apart might cost 3x $20 for example)to the amount of duty & gst you will avoid!
