I get it online at Amazon, I haven't seen it in any retail outlets. Be sure to buy the concentrate, it will make the same equivelent as 16 bottles of the premixed product and you pay the same for shipping as you will for the premixed product.
You can buy direct from Chris Christensen website.....Or google "buy Chris Christensen Ice on Ice" and it should give you a list of online outlets.
And of course CC has a booth at most of the larger shows.....
You can order it from the Chris Christensen website at: http://www.chrissystems.com/index.html
It get's shipped from within Texas. If check distributors there's some that sell their products in stores in Texas.
