I know I'm opening up a can of worms here, but I'll share what my coach told me...not saying it's completely accurate but I'll tell you anyway.
Apparently it is illegal to sell IP products anywhere on the Internet. It is approved only to be sold in an actual clinic.
Headquarters knows, in particular, about plainprotein.com and that's why their website changes quite frequently and/or is out of order. They think a clinic owner (ie. Daisy) orders extra quantities and sells it from an undetectable location.
Again, I know a lot of coaches are in it only for the money, but just wanted to share what I've learned.
