If you own a PlayStation 4, a PlayStation Plus subscription is essentially a must-have. Not only is it required if you want to play games online, but everyone with a PS Plus account also gets a monthly selection of free games direct from Sony, in addition to discounts across the PlayStation Store.

The good news then is that today and tomorrow you can get 15 months of PlayStation Plus membership at half-price in the UK - so what would normally cost £69.98 is instead just £34.99 until midnight tomorrow, 17 July.

Buy 15 months of PlayStation Plus membership for £34.99 from Amazon

This is a great deal even if you're already a PS Plus member, as the code will stack on top of your existing membership, simply adding 15 months on from whenever your account would normally run out.

Membership lets you play multiplayer games online, but also nets you further savings as you get exclusive PS Store discounts, and monthly free games. For July 2018 for example, the free games are Heavy Rain and Absolver on PS4, along with Rayman 3 HD and Extreme Exorcism on PS3, and Zero Escape: Zero Time Dilemma and Space Overlords on PS Vita.

The only caveat is that since this is a Prime Day deal, remember that you'll have to be an Amazon Prime member to take advantage of the price. But if you're not, you can start a free trial of Prime and access the special deal price that way.

If you're an Xbox player you can also save money there too. You can get three months of Xbox Live Gold plus £10 of store credit for just £14.99, or nine months of Xbox Game Pass for £47.49, a saving of 34 percent.
