I've generally had a positive experience with them.

However, I think there was one occassion when I ordered several items that their website showed as being in stock. A day later I got an email that some of the items weren't actually in stock. It was sort of annoying- it took a little bit of back and forth to figure out what colors they actually had in my size in stock. (Some retailers seem to do this- not keep their website fully updated- I assume that if it's in stock on the website they have it, but it's not always the case.)
