If you have a US PSN account, GameDealDaily are back with one of their seriously cheap PSN code deals. You can pick up Destiny, NBA 2K15, Far Cry 4 or LittleBigPlanet 3 for only £22.49 -- though you can only redeem them using a US PSN Account!
The procedure is a little different to the norm. You'll need to pay £22.49 for the '4 games pick 1' voucher code, then redeem said code on the official Sony website for the game you want. Bear in mind that "the redemption website is experiencing issues which may result in users unable to complete the process" so definitely approach with a little caution. Thanks to mango carrot @ HUKD!
