Have absolutely no interest in this game but I have been a spectator for a while on here so maybe I can help some people with this now.
Price looks cheapest yet.
The game appears as £24.99 when in the games menu but when you click on the actual item it shows as the original price. This is corrected in the basket though.
I've been checking sainsburys online each day so I believe this has just went live now so get in quick as sainsburys stock levels are notoriously inconsistent (evidenced by the previous dualshock 4 deal).
