As I ordered my PS4 with Amazon.co.uk they have been sending out discount codes on game purchases.
Today I received a £10 discount voucher for PS4 Call of Duty Ghosts which is £48 to buy so with the voucher £38.
I have the game already so no need for the voucher. It isn't linked to my account only so anyone is free to use it.
For anyone that wants it, I'll PM the first to reply who's been a member for minimum of 6 months.
