It is at the cheapest it has ever been.
It hit €5.06 in March 2025, 18 months ago.
In all that time it has gone from €5.06 to €14.99, and never below.
Today it is at exactly that price, so waiting for it to go lower is not realistic.
Dont Knock Twice for PS4 starts at €4.25 (€4.44 with fees) at Difmark, 78% under the €19.99 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €19.99 (no fees) at Playstation Store.
That €4.25 (€4.44 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Only 3 offers across 3 stores carry it, and thin supply means the price barely moves.
By format: account from €4.25 (€4.44 with fees) and physical edition from €44.99 (no fees) at Amazon DE.
There is no discounted third-party key: the only one available is the official store's, at €19.99 (no fees).
All 3 offers are Global, so the code redeems on any account no matter where it was created.
Critics put it at 52 out of 100, though there are only 19 reviews published so far.
One listing is worth ignoring: the boxed copy that Amazon DE has at €44.99 (no fees) is more than 10 times the cheapest offer and is not what this game costs. The number to work from is €19.99 (no fees) at Playstation Store.
There is no third-party key on offer today, so the choice is between the shared account at €4.25 (€4.44 with fees) at Difmark — cheap, but the game never becomes yours — and paying the official €19.99 (no fees) for a key on your own account. Either is defensible; just know which one you are picking.
