I get my Saint Laurent bags from MyTheresa, for some reason prices are in euro when shipping to New Zealnd and at less than retail price. Though VAT isn't included and NZ customs charges custom import tax on items over NZ$1000 so about NZ$180, but even with that, still much less than retail!
And any orders under NZ$1000, no additional custom charges so definitely a steal.
For example:
Cassandre Matelasse Flap Pouch (black) YSL Europe: €575
Cassandre Matelasse Flap Pouch (black) YSL United States: US$775
Cassandre Matelasse Flap Pouch (black) YSL New Zealand: NZ$1,150
Cassandre Matelasse Flap Pouch (black) YSL MyTheresa shipping to NZ: €438 (no additional custom charges as under NZ$1000)
