I know it's way cheaper to make the stuff, if you can ever manage to use it before it goes bad, but for those like myself who do not, REI currently has the 16 serving size for $21.99.
I picked up a couple cans for my C&O thru later this month. Maybe it'll help someone else out too.
Edit: Notice it's currently free shipping over 50. Nifty! Had customer service add in another can to get the cost down even more. Yipeee.
