I had thought that was a fluke, but nope.
I was having a bad day
Their flavor was Mango CHILI.
Ugh! Spicy Slurpee? No thanks, blech.
I wrote their official email address a sad note about it, and again, in an hour I got a response from a local store explaining that they switch flavors every few months, but she'd try to look into getting another sugar-free one.
I can't think of another store that responds so quickly!
It's silly, but whenever I want a Slurpee, I always have such envy at the machines. If you can drink the normal kind, you get OPTIONS for flavors! You don't have to just take the one they have!
