I had good experience with Mercari to buy an authentic high end perfumes ( Parfums de Marly, Initio) for the fraction of the price, I knew how to authenticate and always requested additional pictures to avoid fakes. Unfortunately, along with honest sellers there are a lot of scammers on mercari.The guy, who got extremely low score on ebay by selling fakes, now pushes all Parfums de Marly, Tom Ford and Chanel perfumes on Mercari. This company does not do anything about it and let poor buyers to be ripped off.
