It's literally half price in the US - until the exchange rate changes anyway.
I have a fab hoodie which cost about £35 (bought in US, would be £75 here).
Ebay is awash with it, but beware dodgy copies.
I don't like their sales pitch or general philosophy though - ie only very young, very slim blonde people need bother trying to wear their clothes, also the stores are so dimly lit you need a miners lamp to find the stuff. I can't wear their t-shirts as they don't go up to my size (UK 14, big boobs) so stuff them.
Their MD was quoted as saying he doesn't want old or ugly people in his stores, and that he will only employ the 'high status' kids from local schools and colleges in his stores, but surveys show he's happy to employ ordinary non-perfect people and even blacks and asians in the back room, where the pay is even poorer.
The stuff is all made in Bangladesh etc, so don't imagine it's worker friendly despite the price - you're lining this guy's pockets, not those of manufacturing or sales staff.
If you're shopping in the US I recommend American Eagle which sells similarly 'preppy' gear at lower prices and in sizes to fit most women. Check out their website, ae.com.
