Any remaining Game Club credits will expire 180 days after the last day of your Game Club membership.
Once your Game Club membership is canceled (effective on the last day of your monthly billing cycle), the My Game Club page of your account will be updated with the expiration date of your Game Club credits.
If you decide to reactivate your membership within that 180 day period, this expiration date will be removed. If you then cancel your membership again, a new 180 day credit expiration period will begin.
This does not include gift certificates or replacement coupons, which will not expire.
