Here's how it works. You first have to purchase a Frosty key tag from your local Wendy's location. That one time purchase will set you back $2. Then, every time you make a Wendy's purchase in 2017, just show your key tag and you'll get a free Jr. Frosty with your order.
Frosty Key Tags are back! For $2 you can help find forever homes for kids in foster care & enjoy free Jr. Frosty treats all year. Cheers! pic.twitter.com/4RtlcEGBnJ— Wendy's (@Wendys) November 22, 2016
The chain says the tags are available at most Wendy's locations.
The Columbus, Ohio based chain says 90 percent of the proceeds from the $2 Frosty promotion will be donated to the Dave Thomas Foundation. The foundation is a non-profit charity to help find forever homes for children in foster care.
