We all like getting something for nothing, so this deal is an absolute belter. You can now get £50 worth of PSN credit for £40, effectively giving you a free tenner to spend on games, DLC and entertainment.
How does it work? Just click this link and follow the instructions! You'll need a PayPal account, though.
As far as I know the £10 saving can be applied to PSN wallet top-ups or actual content. Thanks to BarmyBulldog for this great spot!
