How much does Mortal Sin for PC cost right now?
Mortal Sin for PC starts at €4.68 (€5.14 with fees) at Key4Games, 79% under the €24.50 (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 €6.20 (€7.41 with fees) at Gamivo.
That €4.68 (€5.14 with fees) already includes the GOCDKEYS15 coupon, so apply it at checkout or the store will show you a higher price.
With 24 offers across 15 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 4% under its average of €7.36 since 2023, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for Mortal Sin now or waiting?
That €6.20 (€7.41 with fees) key is at one of its best prices.

Worked out from 1,811 daily records of the Steam Key for Mortal Sin across 12 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Are these stores safe to buy Mortal Sin from?
Worth knowing before you click: Key4Games is cheapest at €4.68 (€5.14 with fees) but has only 37 Trustpilot reviews behind it. If that thin track record bothers you, Difmark has the same shared account at €5.45 (€5.70 with fees) with 14.2k reviews and a 4.1 out of 5.
Which Mortal Sin format should you buy?
With the shared account at Key4Games you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gamivo costs €1.52 (€2.27 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 8 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate Mortal Sin in US?
19 of the 24 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive Mortal Sin offer?
One listing is worth ignoring: the Steam gift that Gamivo has at €27.41 (€29.36 with fees) is more than 5 times the cheapest offer and is not what this game costs. The number to work from is €6.20 (€7.41 with fees) at Gamivo.
