Yippee!! I know you all love this offer. The Wendy’s Frosty Key Tag is back and that means you can buy a Frosty Key Tag for $2 and in return, you will get a FREE Jr. Frosty with ANY Purchase through December 31st, 2019 – yes all the way until next year! Wendy’s will donate 85% of each key tag sold to the Dave Thomas Foundation for Adoption. Very cool!
