Beware of scam

Market have those kind of businesses that they sell certain ordinary thing with extraordinary price. They will add some features that cannot be trace by technology or scientific proof. Some of the examples are ordinary thing but add in fortune teller wisdom, feng shui, religious feature that will bring good or modify for good things for your life. I am not sure why superstitious will become so popular in the main street, among educated people, but I think this is not a good phenomenal because it will draw in con man to create scam, as those "value added" cannot be explained or proof.
