I can back this up - even brick and mortar stores in America are FAR cheaper than in australia. We pay top prices for budget lines of Calvin Klein, Michael Kors, Ralph Lauren...etc.etc
I was in the US recently and I purchased a Calvin Klein suit for $250 @ macys. Went to the Calvin Klein store in melbourne aus and sure enough it was $1000 for the exact same suit. Why is there such a huge difference?
