bazzer: The thing is that you're still liable for GST on the total cost including shipping (less any GST already paid I suppose, i.e. the bank fee or youshop's postage, I'm not sure there's any GST on either of those).
Regardless of what mistake youshop made, the total cost is over $400 so GST is over $60 so you need to pay it.
If sleemanj is correct, then the total cost minus the bank fee is under $400 so gst would be slightly under $60 as a result.
