Have you been using the 711 app? They have tons of freebies and coupons available through their app and mobile alerts. Their newest coupon is through their text alerts. Text SIXFLAGS to 711711, and you will receive a coupon for a free medium slurpee. This one is good through the end of the year, but make sure not to activate it until you are in the store, as it is only good for 15 minutes. YUM!
