I received it as soon as OCUK sent me the invoice. I just didn't realise it, and turned the box inside out trying to find a code lol.
It's on the invoice as a listed bought item, with a stupid long code on it. You need to redeem it through Geforce Experience 3.2? or above and then it will open Battle.net and add it to that.
OK once you order you can log into your account and look at your orders. Look at the one for the 20 series card.
See the red arrow? you'll have the longest game code you've ever seen there. But yeah, that's where it goes and you don't get anything else.
REDEEM YOUR BUNDLE THROUGH GEFORCE EXPERIENCE
1. Install your qualified graphics card.
2. Update or install the latest version of GeForce Experience (Version 3.18 or higher).
3. Open and log in to GeForce Experience.
4. Go to the Account drop-down menu in the top-right and select “REDEEM”.
5. Enter your bundle code from your qualifying bundle purchase.
6. Follow the remaining instructions on screen.
