Redeemables with the wow promotion

Hey there everyone. I was wondering if anyone has had any trouble with receiving their redeemable codes with the new wow promotion. I bought the Razer Kraken v2 pro (which I love) like 2 weeks ago. The shipping page says “delivery in progress” and “product key will be delievered by email.” This seems like a long-ish time. Do I have to register the headset to get the codes? Did I miss something?
