Wendy’s is running their annual Halloween promotion where anyone can get a Boo Book for $1 containing five coupons good for five Jr. Frostys.

The books are being made available in support the Dave Thomas Foundation for Adoption – with 85 cents from each $1 Boo Book sold donated to help find adoptive families for children in foster care.

You can pick up your Boo Book at participating Wendy’s locations until October 31, 2018. The coupons can be redeemed for chocolate or vanilla Jr. Frostys beginning on November 1, 2018, and you’ll have until January 31, 2019 to redeem all your coupons.
