Prospector for PC starts at €3.73 (€3.91 with fees) at Gameboost, a Steam key, which is 74% under the €14.99 (no fees) it costs on the official store.
That €3.73 (€3.91 with fees) already includes the GCDK13 coupon, so apply it at checkout or the store will show you a higher price.
Only 10 offers across 10 stores carry it, and thin supply means the price barely moves.
That €3.73 (€3.91 with fees) key is at its usual price: no bargain, no spike.
Worked out from 1,778 daily records of the Steam Key for Prospector across 11 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.
By format: Steam Key from €3.73 (€3.91 with fees) and Steam Gift from €13.10 (€14.73 with fees).
All 10 offers are Global, so the code redeems on any account no matter where it was created.
