YAY!! Today is Slurp-free day at 7-11! Head over to your local 7-11 between 11am and 7pm today for a free 7.11oz Slurpee!
As my friend suggested, you may benefit from waiting until a rush of school kids goes through after 3pm and the store runs out of the 7.11oz cups then gives you a full size Slurpee for free instead. Apparently it’s worked 3 years in a row. Good luck!
