If you have a 7-Eleven nearby, I highly recommend you download the 7-Eleven app on your phone. They offer great freebies periodically. Right now they’re offering a free Mountain Dew Big Gulp to people with their app. This offer is available today through 7/3/13.
Once you download the app, click the $ at the top and it will show you all the offers. You’ll see the freebie for the Mountain Dew Big Gulp but don’t click to redeem it until you are at the store. It’s only good for 15 minutes once you hit redeem.
