How do you celebrate National Frozen Yogurt Day? With frozen yogurt, of course! Menchie’s Frozen Yogurt is dishing up six ounces of the sweet stuff with toppings for FREE on Feb. 1 from 4 p.m. to 7 p.m. (If your sweet tooth swirls more than six ounces, just pay the difference.) Limit one cup per customer at participating locations. For shops nationwide, click here.
