Participating Wendy's locations offer a Jr. Frosty Coupon Book for $1. Each book includes five coupons that can be redeemed for a freeJr. Frosty treat. That's tied with our mention from last October and the first offer we've seen for Wendy's Jr. Frostys this year. Proceeds will benefit the Dave Thomas Foundation for Adoption.
