Sorry for the late reply. I agre with Wayne, as far as I know, the only place that sell food online is Happy Koi.
We do sell Aquanutro at R 15/kilo but it is not viable for us to send it by mail as our markup is very small.
My suggestion is to stock up whenever you come down to CT. I am sure you are quite used to large distances living on the edge of the barren Richtersveld?
