Marketplace and reseller prices are the lowest offer at the time of the check. On marketplaces the seller is a third party: check the seller's rating before buying.
Cheapest in pounds and dollars
The same game at stores that sell to buyers in the UK and the US, in the price they charge there. We do not convert: these are the amounts at the checkout. Most key marketplaces publish euro prices only, so pound and dollar prices come from official stores, authorised resellers and Kinguin, and can be higher than the EU price above. That is the reach of our data, not the state of the market.

Console keys for the same game
These are keys for consoles, not for PC. They are listed apart and are never counted as the lowest price on this page: an Xbox or PlayStation key does not activate on Steam.
Other regions and currencies
Sold from another country's storefront or for a region that does not cover the EU. Paying in pounds or dollars is your own business — a key for the wrong region is not: check the region before you buy.
