I went to Costco today for some groceries shopping. And on top of the coach, there's prada and chole purses In fine jewelery, I see Cartier tank with diamonds and 2 other Cartier watches all diamonds, I also saw some Gucci watches, michele ( on top of the normal Omega for men). I know costco is not an authorized re-seller so how did they get these?? The watch look 100% authentic, I was wearing my michele at the time and it looks exactly the same as the one in display. Is it legal for them to sell these watches? Do these big brand names know their watches is on sale next to diapers and milk? I am just shocked at seeing Cartier tank there.
