7-Eleven is offering free slurpees today. From 11am to 7pm local time, you get a free slurpee. On top of that, if you scan the 7-eleven app in store while doing this you also get another free slurpee that can be claimed between 7/12-8/12. See the promotion here.

They do this every year. Two free slurpees for everyone.
