@Kaapstad Cheers.
I got a code in an email not long after ordering mine, You then have to go to AMD's reward website which is linked in the e-mail. I'd hurry up and get on with doing it if I was you, No-ones coming close to OCUK on price when you take the games into account and the offer may not be around much longer.

How to claim the codes.
1, I received an email with codes within a few hours of ordering my GPU. The email contains the codes & a link to the AMD rewards web page where I have to register.
2, While registering I was asked for a mobile phone number which you do not have to give, I didn't give mine & after registering it told me I'd have to wait 24 hours before the account activated because I did not give them my mobile phone number, I've now waited over 24 hours.
3, 24+ hours later I use the AMD Rewards link from the original email and I'm asked to Log In which I do.
4, I now have a window they want me to put the code from the email in and a submit button which I do.
5, Now there's a large window spilt in two, The left side has the name of the 3 games in the bundle & as I pick each one the game appears on the right side with an add to cart button. I go through them adding them to the cart. Then I press the next button.
6, This takes me to a page with the 3 games showing and a confirm my selection box that I tick & then I press next.
7, I then get the following page confirming the games are being added to my AMD Rewards account, telling me which platform the games are on & saying I'll be contacted with the game codes as the content becomes available.
