The iPhone X may be a few years old by now, but it's an iPhone. That means it holds its value better than Spider-Man holds onto walls, because people just love to buy iPhones and Apple isn't fond of price drops when it doesn't need them. So it's nice to see a 25% discount hit Amazon for Black Friday.
The deal covers the 64GB iPhone X in silver, and lowers the price from £899 to £639 - saving you £260 from the normal price. A normal price which also happens to be £200 lower than the original retail price when it debuted in 2017.
