I placed an order today and got free shipping to NZ....

But if I place the same order from a different computer, the shipping is not free (signed in).
And, they have a search option I've not seen previously...

So, you can filter products with 'free international shipping'.
But, the filter does not work as I do not seem to get free shipping on the filtered goods . I'm guessing it might be free to some countries but not NZ , perhaps. But, it should be smart enough to look at the account address and figure it out.
