I was just researching that site earlier today... Someone on another forum said they sell IP foods at "much better prices" (she meant actual IP foods but she was misinformed!)
However, what I noticed on many of the products they sell is that they are other brands that most of us would recognize (Proti Diet, Proti Thin, HealthSmart, WLS, etc.... LOTS I recognize from Nashua Nutrition). They are selling them for $4-8 MORE than Nashua sells them. And I also didn't care for the fact that they did not identify the brands... It was almost presented as if they were all their own products!
Anyway, if you see something on there you like, I suggest checking to see if it is less costly elsewhere first, then decide!
