If you’ve been sitting on the fence then now’s the time to strike. Shopping around, you can probably find a physical copy for £25, though nothing quite beats the 80% offered by PSN.
UPDATE 3: It appears this was a mistake by Sony after all as the offer has now been removed and the page can no longer be accessed.
UPDATE 2: Our mistake, the offer is still live, you just need to be signed in with a PlayStation Plus subscription in order to see this price, with it looking like Sony are kicking off another round of double discount offers on the store today.
There’s still the chance it’s been a bit of a mistake, so you might want to hurry…
UPDATE: You snooze you lose, the price has now increased to £29.99. Presumably someone pressed the wrong button and made a typo earlier.
