Reportedly the Free Frosty Trick Or Treat booklets are back! These cost $1 and contain five coupons for free Jr. Frosties! Coupons are valid between 11/1-2/1/12. Stop in at your Wendy’s now (before they're all gone!) and pick up your booklet for later!
Update: Sara commented that the coupon booklet she purchased actually has TEN coupons in it -- even better!
Thanks, Couponing For 4!
