[Utah-astronomy] Off topic- Need to find Hyfax sources

Hello everyone, I was wondering if any of you knew anything about Hyfax material I'm asking for a friend personally I've never heard of the stuff. He sent me this link for it http://www.tse-ok.com/natural-protech-1000 But as you can see it's pretty pricey. Any tips on a cheaper or even more local place to get this stuff? I appreciate it. Howard PS: To mention some astronomy it's been fun this week watching the moon in the morning as I take the kids to school it's led to some very good teaching opportunities about Lunar phases and the Earths rotation.
