How much does Prime Monster for PC cost right now?
Prime Monster for PC starts at €7.97 (€8.33 with fees) at Difmark, 40% under the €13.99 (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 €8.27 (€8.65 with fees) at Gameboost.
Of every month we have on record, this is the cheapest.
That €7.97 (€8.33 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 17 offers across 14 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.

Worked out from 1,389 daily records of the Steam Key for Prime Monster across 14 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.
Which Prime Monster format should you buy?
With the shared account at Difmark 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 Gameboost costs €0.30 (€0.32 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.
Can you activate Prime Monster in US?
13 of the 17 offers work on US — the Global ones plus the ones issued for your own region.
