BuySpry via eBay offers the refurbished Unlocked Apple iPhone X 64GB GSM Smartphone in Space Grey or Silver for $629.99 with free shipping. That's the lowest price we could find by $70 and the best price we've seen for the iPhone X 64GB. (For further comparison, it's $45 under last week's mention of the 4G LTE model.) It has an A11 Bionic chip neural engine, 12-megapixel dual rear camera with dual OIS, wireless charging, and Bluetooth 5.0.

It includes a 60-day warranty, although it's unclear who backs it.
