KXTV, Sacramento, Calif.

Wendy’s Frosty lovers, rejoice. Beginning next year, anyone who enjoys the frozen treat can do so for free, for a one-time payment of just $2.

The $2 key tag purchase guarantees a Jr. Frosty with any purchase for the entire year, as well as the knowledge that every 90 cents on the dollar will go toward the Dave Thomas Foundation, the not-for-profit created by the chain’s founder, to help find forever homes for children in foster care.

The Frosty key tags are available for purchase through the holidays while supplies lasts.

According to Wendy's, the key tags can be purchased at most Wendy’s location, but they are also available for purchase on the foundation website.
