BuySpry via eBay offers the open-box Unlocked Apple iPhone X 64GB GSM Phone in Silver for $635.99 with free shipping. That's $49 under our March mention and the best deal we've seen. (It's $164 less than the lowest price we could find for a sealed unit.) It has an A11 Bionic chip neural engine, 12-megapixel dual rear camera with dual OIS, wireless charging, and Bluetooth 5.0. A 60-day BuySpry warranty applies. It's essentially new but may not come in its original packaging.
