This promo definitely won’t leave you in the cold…well, maybe a bit frosty. You can get a FREE Jr. Frosty (reg. 99 cents at most locations) with any purchase at Wendy’s, through August 31. All you have to do is purchase a Frosty Key Tag for just $1 at a participating location. (The cool tags are available through mid-April, while supplies last.) It’s even sweeter because all of the proceeds benefit the Dave Thomas Foundation for Adoption. Then, every time you visit Wendy’s through the end of August, you’ll get the sweet treat for FREE. The offer is limited to one per transaction, per visit, per key tag. This deal pays for itself in just one visit. However, if you frequent Wendy’s at least once a week, you could easily save more than $20 by the end of August. We think it might be good investment to buy one for each family member. If anything, the proceeds are going to an important cause — helping kids find a good, loving family to call home.
