I was just looking at Craigslist myself. Any thoughts on the risk of buying BNIB from there?
Ive never really bought a phone from craigslist (only to sell, though), but the only skeptical part i have with "BNIB" iphones is if they have previously been used before, and was wrapped.
If you venture deeper into the cave of craigslist, you would see some "wholesalers" wanting to buy as many iphones as they possibly can. I am just speculating, but my best guess is that they have some fake outer frame parts and a way to wrap the thing, then they charge you premium for it.
Also, there are those really negligible buyers who dont really check the phone for water damage/stolen (which is a biggie... make sure to check the imei as well as call apple for the web order number if they claim that they bought it from apple)
Anyone can forge a receipt. It would be much more reliable if you would demand them to go onto the apple store, log in with their account, and literally see the phone being ordered by apple on the web.
You can never be too careful...even now im having second thoughts about this, but I would make sure to take every cautionary measure.
Good luck friend
