I talked to a seller (Hypee Hb), he's selling a MacBook and a iPhone x but with the specs, so I asked him for the specs of the mac and gigs of iPhone, he told me the specs wasn't what i wanted, and he told me that he has another brand new mac **inch, so i told him the specs I'm looking for, he said the mac he has is exactly it, i was surprised by the coincident, wondering how much is it? he said $**** brand new **** unopened. that less than half of the market price, I started to feel that this might be the same scan as those iPhone scans, sell something cheap and do the trades offline or through other apps. so I ask him whether or not we're doing the trades here in mercari? so i can tell right away if it's legit. and MY MESSAGES ARE DELETED BY ADMIN???? what's going on? I started using mercari almost half year ago, and bought over ** items on mercari, in fact, I just bought a similar mac but older model a few days ago, I reported many iPhone scans also, and this seller, he started this month, probably yesterday, and that was his first item! you deleted my message instead do more investgation on him??
