Is it worth buying the Steam Key for Oxygen now or waiting?
That €1.34 (€1.63 with fees) key is at one of its best prices.
- Those €1.34 (€1.63 with fees) are 37% below what it usually costs, measured on the store price.
- 9 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
- Not counting today, only 39 days out of the 472 days on record were this cheap or cheaper; the lowest it has ever cost is €1.14.
Worked out from 2,504 daily records of the Steam Key for Oxygen 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 Oxygen from?
The cheapest, €0.49 (€0.76 with fees) at Key4Games, is only €0.04 with fees below Kinguin — these two undercut each other by cents rather than by real money. For that difference Kinguin is the safer pick: same Steam key at €0.42 (€0.80 with fees), backed by 124.5k reviews and 4.6 out of 5, against the 37 of the cheapest.
Which Oxygen format should you buy?
The cheapest offer is already a key for your own account: €0.49 (€0.76 with fees) at Key4Games, so there is no reason to weigh up a shared account here.
The 3 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 Oxygen in US?
14 of the 20 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive Oxygen offer?
One listing is worth ignoring: the Steam gift that Difmark Digital Keys has at €15.62 (€16.32 with fees) is more than 21 times the cheapest offer and is not what this game costs. The number to work from is €0.49 (€0.76 with fees) at Key4Games.
