Final prices with fees and discounts applied
Ground Zero for PC starts at €8.39 (€8.77 with fees) at Difmark, 30% under the €12.59 (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 €12.59 (no fees) at Steam.
That €8.39 (€8.77 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Just 10 stores stock it, 10 offers in all, so there is little here to push the price either way.
That €12.59 (no fees) key is at its usual price: no bargain, no spike.
Worked out from 1,348 daily records of the Steam Key for Ground Zero across 10 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.
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 Steam costs €4.20 (€3.82 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.
All 10 offers are Global, so the code redeems on any account no matter where it was created.
