I like them too. Their slim fit is perfect for me off the rack, if you are shipping to the US, you save VAT, my last bunch of shirts on sale cost me under $40 per shirt shipped, though there was a delay due to some strange credit card question they had, and their customer service was not great. Once it was taken care of, I had the shirts in a week.
Quality seems pretty good, especially for that price point, there's not much you can do with a $37 shirt. Mine have held up well to washing, and far outperform my CT shirts.
There may still be a working discount code around here. Do a search.
