Wendy's $1 Halloween Coupon Books Good for Up to 10 Jr. Frosties

Wendy's is once again offering $1 Halloween Coupon Books, each with five or 10 (varying with location) free Jr. Frosty coupons that you can hand out for Halloween (or use all yourself).

85 cents out of each $1 spent on the coupon books goes to the Dave Thomas Foundation for Adoption, which helps find families for children waiting in foster care.

The coupon books can be purchased from participating Wendy's restaurants through November 1, 2015.

A Jr. Frosty is about 6 fluid ounces or half the size of a small Frosty.
