I just saw a massive discount for PS+ subscribers on offer at the UK / EURO PStore.
57% off the original selling price.
Not sure how long this is available, but if you don't have it yet, buy it now at this price, and download it at your leisure , as it will be in your purchase history [That's what I'm doing with the PS VR games that are going cheap-or free for PS+ memebers, even though I don't own a VR headset....I'll have something to play without cost if I eventually get one]
