If you have a fan of Wendy's Frosty in your family, just $2 could get you the perfect stocking stuffer.

Wendy's is offering a keytag for $2 that will allow the person to get free Jr. Frostys for all of 2017.

The company says 90% of the money will go towards the Dave Thomas Foundation, which supports foster children.
