With so many lucky 7s and 11s involved in this promotion, you might be tempted to scratch a few lottery tickets at the same time. 7-Eleven is celebrating its 89th birthday by giving everyone a FREE small Slurpee (7.11-oz.) on July 11, from 11 a.m. to 7 p.m. (If you really want to celebrate, sip on its limited-edition Birthday Cake flavor.) In years past, many locations drain their Slurpee machines early, so plan accordingly. The offer is limited to one per customer at participating locations, while supplies last. There are many convenient locations everywhere. However, if you can’t find one, here’s a store locater.
