Club Nintendo
Members of Club Nintendo might've earned credits (referred to as "Coins" or "Stars" depending on region) which might've been traded in for special edition items which were available only at Club Nintendo. Earning these credits was done primarily by submitting codes found on Nintendo products and systems, and for completing related surveys provided by the Club Nintendo websites. The Club Nintendo reward items included playing cards, tote bags, downloadable and physical games, various merchandise based on Nintendo's intellectual properties, special gaming accessories, limited promotions, and warranty extensions on select Nintendo products.
