I just ordered some Icebreaker from them through eBay.
They have the cheapest prices I have found.
With my receipt was a coupon code "Nice08" for $10 off for any purchase over $100.
Many items are marked as free shipping. On the eBay listing it said that I would receive 25% off the shipping on a second item. I ordered two items, one item offered free shipping, one did not. I didn't get the 25% off the second item (I guess because the second item was free shipping) and they shipped separately.
