That actually what some of them do and will pretend there is nothing wrong with the product, some will even sell products that they have long have and still tell you they just got it , I do not fall for all these because I know what humans are capable of doing just to make sales.That's the reality that happens a lot here too. Even some traders hide defects in their products and still sell them at normal product prices. I had bought a product whose packaging had been torn, I was disappointed.
