If the retailer you purchased the cards from is a participating retailer in an AMD promotion, and they have not exhausted their allowance of promotional items, then the retailer will provide any promotional items.
This promotion seems to be a bit of a sham, AMD should be providing these codes and not the vendors.
I ordered two qualifying products from Canada Computers, terrible company, never order from them - I've had nothing but bad experiences with them.
WIth my two products, I should have received 2 game codes and 2 Xbox game passcodes. It was like pulling teeth, it took me 3 weeks to get just 1 game code and 1 xbox game pass code. They refused to send me anything else and then started sending me already used codes.
I'm going to contact AMD about this but I'm not hopeful.
