You have to be careful when you read "certification", "approval", "approved" etc etc etc. They all have a well paid lawyer/marketing rep wording everything. For example, theres a huge sine in the shopping window that says 70% off!!!The buyer heads for the front doors, wow 70% off he says...AHHH, but lets look a little closer, in teenie weanie print under 70% it says "up to"....Hmmmmm So he walks in the store and everything is 40%, he asks the cashier what about 70%, she tells him, ohh thats the one rack off clothes in the back with 10 shirts on it.So the 2 little words "up to" gets them off the hook legally. Marketers are very canny in how they word/disquise what really is going on. The consumer must pay very close attention to what is written, less you be deceived.
