About RDK
RDK is an independent game price comparison site. We track offers from official stores and established key marketplaces, and put them side by side so you can see the whole market for a game before you buy.
Buying game keys online has a trust problem: hidden checkout fees, region-locked keys that won't activate, and "deals" that quietly point at a different edition. So we show the details other comparison sites tend to bury. Every offer on this site lists its edition, region and the platform the key activates on.
How offers are ranked
The cheapest in-stock offer always tops the list. We may earn a commission when you buy through our links, but commission never changes the order and a store can't pay to rank higher. Out-of-stock offers are shown greyed out at the bottom, and offers we haven't been able to re-confirm recently are automatically marked out of stock.
Where the data comes from
Prices come directly from each store's official data feeds and APIs, refreshed automatically. Each game page shows when its prices were last checked, and our price history charts track how an offer has moved over time, so you can tell a genuine low from a marked-up "discount".
We also write our own store guides covering who each seller is, where their keys come from, and what fees to expect at checkout, and we collect reviews from real buyers. You'll find the store guides linked in the footer.
