Looks like a good deal on one of the best games. You should look for this game instore rather shopping it online. John lewis charges £2 for click & collect service which is a shame. You can get this delivered free if you shop at John lewis for £30 or more. I have dropped an email to Local shop (Solihull) to find out if the game is available in Store.
This is new game with 3 year warranty from John Lewis. You may find pre-owned game £1 cheaper online but for new game I didn't see any deal cheaper than this. Tesco, Game, Amazon, and all other retailers (i know) are charging lot more.
Unfortunately there is no Quidco cashback, and I am not sure if the same deal is available on PS4.
