Gather round, Frosty lovers, because we have got some great news for you: The restaurant is once again offering up their famed chocolate and vanilla soft serve treats on the house to customers for a whole year, for just $2. Yes, that’s right, just $2.

If you buy Wendy’s $2 “key tag” from a participating location (the list can be found, here), you will receive a free Junior Frosty Treat with every purchase you make at the fast food chain during 2019. Obviously, you’ll need to flash your tag when ordering—so make sure and add that baby to your key ring.

Dave Thomas believed, “These children are not someone else’s responsibility. They are our responsibility.” Help us realize Dave’s vision that every child has a permanent home and a loving family.

Plus, you can feel really good about your increased Frosty consumption in 2019, because Wendy’s promises that 85 percent of your $2 key tag will go to the Dave Thomas Foundation for Adoption.

The nonprofit foster care organization helps find adoptive homes for children in foster care. It was created in 1992 by Wendy’s founder Dave Thomas, who was adopted as a child.

To nab the free Frostys in 2019, you’ll need to purchase your tag before December 31, 2018. It’ll be valid until December 13, 2019. Use it wisely—and often!

Go forth and Frosty, my friends.
