I keep hearing here on HN that people _don't_ need the latest and greatest in phones, so I think these (refurbished) iPhones available on BestBuy are a great deal. And these are supported by the latest iOS version [2] [3], too.
There are also refurbished phones available from Apple themselves, but they don't seem to provide the older generation (iPhone 7, SE, etc.) and the cheapest available at this time is for $530, as compared to BestBuy's iPhone SE 2nd Gen for $35.
