Do you plan on activating it? Or just a wifi device? If so go check out TotalWireless. It’s a 3rd party phone carrier that’s owned by Verizon. I got a 6s plus a couple years ago from them so they usually carry a bunch of older devices new. They might still have 8 plus’s for sale new there, but don’t quote me. Not sure how their supply has changed but they had them last year when I was using their service before I switched to T-Mobile.
