Littlewoods sell the 1-year PS+ subscription for £49.99 and you can use a £20 discount for new accounts.
So the last time I bought PSN cards was about 3 years ago on a great deal from here, and that subscription is very sadly running out. I came back to my trusty HUKD for some sweet PSN deals but nothing quite hit that low spot.
Anyway, I went on my own deal hunting adventure and came across Littlewoods who sell a year's subscription for £49.99, which you can buy cheaper directly from Sony. However, for new credit accounts with Littlewoods you can get a £20 off a £40 spend. Perfect. Although I wanted to wait until the discount was confirmed before I posted the deal here. And, good news, it has - there is a £20 refund on my credit card already.
Quidco has also tracked at £0.42 (1%) but should track at 7% for new customers - which I'll be raising a ticket for if it doesn't adjust.
