TCBY is marking National Froyo Day by giving away a free 6 oz serving of frozen yogurt to each customer who visits a participating store on February 6th. This promotion allows customers to indulge in TCBY's delicious frozen yogurt without the need to make a purchase. For those who choose to serve themselves at self-serve locations, it's important to note that the weight of any toppings will count towards the 6 oz limit. Customers will be responsible for paying any difference if their serving exceeds this weight. This special offer from TCBY provides a perfect opportunity for frozen yogurt enthusiasts to celebrate National Froyo Day and enjoy a complimentary treat from one of the leading frozen yogurt chains.
