I had no trouble at all signing up with CDKeys on their easy to use website.
Paypal means i have no concerns about buying securely, and the key was delivered straight away and worked instantly on Steam with zero issues.
Saved me a huge chunk on price (Death Stranding Director's Cut cost me just over £11 vs Steam's £30+) so i'll be buying from CDKey's again!
Thank you Craig, enjoy Death Stranding
