The iPhone X is expensive in the U.S., but that's nothing compared to prices in some other markets. Case in point: The United Kingdom. There, the 64GB iPhone X costs £999 while the 256GB variant costs £1,149. That's an absolutely insane price difference: 999 British pounds is about 1,330 U.S. dollars, and 1,149 pounds is 1,529 dollars. This means that the 64GB iPhone X costs $331 more in the UK, and the 256GB iPhone X costs a whopping $380 more in the UK.
