Saw this being promoted on twitter. Just posting it and hoping it helps other ozBargainers. I don't think I'll wealthy enough to buy this label.
Just use the code AUFREESHIP to get the Australian shipping for free, normally a flat rate of $10.
Also, you can use STYLE40 to save 40% on sale items, not sure if the two are stack-able.
Edit: Not stackable so please choose wisely.
I don't know if J Crew still does this but they used to hugely inflate the prices on their international site. For example a shirt would be $40 with a 30% coupon available on top on their US site, the same shirt would be $90 on the international site and you can't use the coupon.
Back then I emailed asking how the shipping was "free" when they have more than tripled the prices. Got a pretty arrogant response and haven't been back to their site since.
