It's seems that Amazon have priced matched the PlayStation Store (US & CDN) on the Realm Reborn game. It's evidently an error as the complete package is double this price on both US and CDN.
Obviously the game would require a US PlayStation account, but once downloaded can be played on your UK account. For instructions on how to create a US account, please see the following link >>PS4: How To Buy US Digital PSN Games
You'll also need a US FF XIV account too :)
