Summer is ending, but there's still plenty of time to grab a cool treat. Dairy Queen just announced their Pumpkin Pie Blizzard is returning soon and they have even better news: now through Labor Day, you can grab BOGO ice cream at any participating DQ location simply by using their app.

According to Thrillist, the chain is offering buy one, get one free small sundaes and BOGO shakes or malts of any size under the "deals" section of their mobile app. The mobile coupon is good all this week, through September 2.

If you don't already have the app, you're in for another treat (literally): you can score a free blizzard just by downloading the app, no strings attached. Use it for the Pumpkin Pie Blizard or, my personal favorite, the Cookie Dough Blizzard. Yum.
