Damn. They had a nice black Slimfit button down shirt for $68. I guess I have to find some place else then.
Honestly, $68 is a bit steep to pay for a shirt of A|X's quality, but they (seem to) have sales fairly frequently. They can often be had for about $30 to $40.
That said, I generally like the cut of A|X button-down shirts more than most shirts around that spectrum (that is, so-called mall brands). Banana Republic shirts tend to be a bit boxier and longer, and the quality of BR shirts aren't anything to cheer about. (J. Crew may offer a decent slim-fitting shirt, although I don't know for sure; I have a couple of last season's flannels and they fit well, especially for flannels.)
A|X's stuff also tends to be a little more heavily branded and a little flashier, which is where (I think) a lot of the forum's animosty stems from. A|X does make stuff that isn't so ostentatious, and generally it's fine.
So, bottom line: I wouldn't ever spend $100 or so for an A|X shirt, because for that price you can get really good shirts if you look hard enough. But for $30 or $40, I'd be willing to get one because I like the cut and the length with the understanding that it's not going to be an outstanding shirt. But as a poster mentioned earlier, with the proper care, even a shirt of mediocre quality will last a while.
