The iPhone X is now Available in Kuwait and below you will find the best prices of retailers selling them, you will see a difference compared to U.S prices, but if you compare it with taxes and shipping the prices we have here in Kuwait isn’t that bad.
The iPhone X 64GB = 352.750KWD

You can either buy them online or go to the store and buy it, but if you want to buy it online below are the links of the websites
I advice to buy it from Alpha store as they are the authorized reseller for Apple here in Kuwait and you will get the Apple warranty which is the best warranty you can get.
