I just realised that I also collect Ralph Lauren polo shirts as they are often cheaper overseas .
I thought I was the only one! There are a heap of 10-30% discount codes around for RL's website. I have a dozen or so 'gift boxes' at home now from these shirts. With free shipping, there's seldom a hotel I stay at in the USA where boxes of the stuff doesn't rock up for me. I bought a RL jacket on my last US trip for around $195. The same one here is over $680. Retailers here can go jump, even if GST is added to imports, they're still going to be cheaper!
