I got to upgrade this year, so my iPhone 14 Pro Max is now available. Always in a case. In great shape. In fact, I have a brand-new Apple Leather MagSafe case for it. Original cost was something like $79. I'll include it.
How do I arrive at this price? Ebay sales for the
most recent 53 units were between $539 and $1100 including tax and shipping. That is a clear sample of what people are willing to pay even without holding the unit. The mean is $711 and the median is $819. So $750 feels like a reasonable ask. Give it some thought, and ask questions if you have them.
