Interesting look at what's going on behind the scenes. I always avoid all these strange brands, but then again maybe I'm a sucker for over-paying for a label. I'm sure that's true in some cases at least.
One thing I'm definitely willing to pay a premium for is consistency and that's getting harder to find not only just on Amazon but even on some name-brand sites (looking at you nike.com). When I need a new pair of jeans it saves so much time to just grab a pair of 513's in my size instead of wading through a marketplace of random crap.
