Qualified sales include games and Game Club credits, but not CDs. Commissions on purchases of Game Club credits are credited to your account once the credit is redeemed. If your referred customer purchases a Game Club credit, commission will not be added to your earnings until the customer redeems the credit for a game.
All consumers who have not purchased a game in the last 12 months are eligible to be referred. If a customer visits websites of multiple Affiliates, s/he will be bound to the Affiliate s/he was last referred by prior to purchase.
