PlayStation Plus (365 days) | CDKeys.com | £31.49 (RRP: £39.99)
You'll need a PlayStation Plus to play the majority of PS4 games online, but Sony's secret weapon is so much more than that. Offering a cycling rotation of free games across PS3, PS4 and Vita, not to mention discounts and perks, PlayStation Plus pays for itself within a matter of weeks. To put this in perspective: BioShock Infinite, Metro: Last Light, Outlast, Dynasty Warriors Next and more are all currently available to download if you're a member.
Better yet, you can now save the best part of a tenner on a yearly subscription from CDkeys.com. Thanks to POWYSWALES @ HUKD!
This deal has now expired, but Xbox 360 and Xbox One owners should note that CDkeys are also offering a year of Xbox Live Gold subscription for £26.99. Thanks Tsung & Late!
