7-Eleven: Free Medium Slurpee
UPDATE: This offer seems to be working even if you used it the last time I posted it!!!
Get a FREE medium Slurpee at 7-Eleven when you text SIXFLAGS to 711711 (offer expires 12/31/14).
If its your first time doing text offers from 7-Eleven you will receive a text then reply Y and then you’ll get another text with a link to the coupon (so you’ll need a smart phone), and only click “Redeem Offer” when you are ready to use it, as its only valid for 15 minutes after that.
