Pscheel,
buy it from Premium!
I believe this is the whole reason why Rod hooked up with Premium Aquatics to distribute his food all across the US. If you want it, you can buy it from Premium. It will costya $30 bucks, but you can get it anytime. If ya wanna drive for it, Rod prefers if you only want to pick up a bag or two. Plenty to keep any aquarium stocked for a while.
If you have ever seen the magic brew being prepared, it's a pain in the rump, time consuming, and portions / sizes / mixes are something Rod is very mindful of. Definately worth the premium, as the fish and following can attest.
Also, Pscheel, I will take a leisurely 12-15 minute flight there from Naperville or Schaumburg. Happy to have you tag along for the ride - a few people have. The trip is worth the time, though you get your fish and corals addicted to the reef crack that Rod sells. (DT's, oyster eggs, mysis, all kinds of other crap that Rod puts in it)...
