Free Lemonade with 7-Eleven app tomorrow, August 20

Heads up, mobile users!  Tomorrow only (August 20), on the 7-Eleven app, you'll find a coupon for a free 16 oz bottle of Snapple Lemon Daze, in honor of National Lemonade Day. 

Don't have the app?  It's available for iOS and Android smart phones.  Make that expensive smart phone pay you back by downloading the app and cashing in on a freebie tomorrow.  7-Eleven offers freebies periodically via the app, so it's worth the time to download.
