A friend of mine has one for sale. $1380. AS NEW. includes genuine Apple leather cover. I vouch for the seller and the phone completely.
It's completely legit, perfect condition, sourced locally through normal retailer. Someone just realised the day they bought it they wanted an X instead.
If you're interested and aren't going to offer less, please get in touch with me and I'll put you on to her. She's tried selling it on Facebook marketplace, but out of about 20 responses, only one was semi-legit and that person backed out after rescheduling the pickup at least once.
FB Marketplace is truly an awful place...
