SS doesn't really operate this way. Australia buys up a lot of the SS market (proportional to population size), and we operate on opposite seasons to you. Coupled with their physical outlet store in Roermond; unless they rebuild their online outlet store, I'd be surprised to see sales.
When you order >$1000, SS cover the import duty. Is it sad that I've ordered enough >$1,000 SS orders that I know this? Stichy - you'd want to look at Havana/Lazio/Sienna for pants - ignore Napoli/Washington - no thigh allowance.
