With this thought process, you would also feel that a Fiat 500 ($10,000) is of the same quality as a La Ferrari (2,000,000) , although owned by the same company (FCAU) and use the same ingredients? Not !
Indeed. I think the Fiat 500 is more reliable. Seriously.
About expensive shaving products; I am sure that there is a large markup due to marketing and smaller volumes. I really wonder if the net price of the ingredients is that much different.
