COLUMBUS (WCMH) — Wendy’s Frosty lovers, this is the news you’ve been waiting for.

Now is the time to snag unlimited “free” Frosty treats from Wendy’s for an entire year.

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 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.

The key tags can be purchased at most Wendy’s locations.
