Well, for one thing, being that they're compatmentalised, replacement/resupply is a lot easier and cheaper... replace the component you use instead of the whole kit. And there's also the fact that many folks don't realize the need for an entire kit. These "specialty" kits fill the niche for athletes, hikers, comuters, and a whole lot more... they're not just marketing to ETS members...they're shooting for a much larger demographic <img src="/images/graemlins/wink.gif" alt="" />
