Final prices with fees and discounts applied
Day of Defeat Source for PC starts at €1.95 (no fees) at Steam, a Steam key.
We have never recorded it cheaper than this.
Supply is thin — 4 offers from 4 stores — and thin supply keeps prices steady rather than falling.
That €1.95 (no fees) key is at one of its best prices.
Worked out from 1,718 daily records of the Steam Key for Day of Defeat Source across 7 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 €1.95 (no fees) and Steam Gift from €1.83 (€2.64 with fees).
3 of the 4 offers work on US — the Global ones plus the ones issued for your own region.
