7-Eleven is offering customers a free 7.11-ounce frozen Slurpee drink today to help celebrate its 85th birthday.

The free Slurpee offer is available from 11 a.m. until 7 p.m. at participating convenience stores while supplies last. 7-Eleven began offering free Slurpees on July 11 on its 75th birthday in 2002, and it's become a big hit with customers. 

There are three 7-Eleven stores in St. Peters:

• 6680 Mexico Road
• 610 Jungermann Road
• 7901 Mexico Road

Or if you're in another area tomorrow, you can download timeRAZOR, a free events app, which will provide its users with 7-Eleven store locations across Missouri that will be offering free Slurpees. The app is available for iPhone and Android phones.
