Every year Wendy’s hosts a Boo Books campaign to raise money for the Dave Thomas Foundation for Adoption. The promotion lasts for five weeks during September and October.
Each Boo Book coupon book costs $1 and contains coupons for five free Frosties. There’s no limit to how many Boo Books you can purchase. I’ve heard that some people actually buy enough booklets to hand out to trick-or-treaters on Halloween. It’s one of our favorite noncandy Halloween treats.
Wendy’s Boo Books is one of the best Wendy’s deals all year.
Get five Jr. Frosties for $1 when you purchase a Wendy’s Boo Book.

You can purchase a Wendy’s Boo Book for $1.00 in person, or as part of an online pickup or delivery order. No additional purchase necessary. Each Boo Book will get you five 6-oz Jr. Frosties (regularly $1.89 each), which means you’ll be getting an 89.4% discount on your next five Frosties.
Boo Books are only available from Sept. 1 to Oct. 31, so you should get yours while supplies last.
Note: $0.85 of every $1.00 Boo Books purchase goes to the Dave Thomas Foundation for Adoption.
Wendy’s Boo Books coupons expire at the end of the year.

Unfortunately, you won’t be able to keep your Boo Books forever. Wendy’s Boo Books expire at the end of the year you buy them.
Since the coupons expire on Dec. 31, it isn’t going to make the best stocking stuffer — unless you’ve got plans to redeem all five coupons quickly after Christmas.
You won’t be able to get a discount on other Frosties with your Boo Book coupon.

Unfortunately, you won’t be able to use your Wendy’s Boo Book coupon on anything other than a Jr. Frosty. For example, you can’t take off the price of a Jr. Frosty to a Large Frosty.
Also, you can only redeem these coupons in restaurants at the counter or via the drive-thru. No online orders can be used to redeem your free Jr. Frosty.
If you missed out on Wendy’s Boo Books, you can get a Wendy’s Key Tag for more free Frosties in November.

If you’re still craving more Frosties, you can get a Wendy’s Key Tag between Nov. 1 – Jan. 31 for $2. That’ll get you free Jr. Frosties for the next calendar year. No additional purchase necessary, and you can get as many Key Tags as you want. Only one free Frosty per Key Tag a day.
Still need more Frosties? Sign up for the Wendy’s Rewards Program.

The Wendy’s Rewards program is a great program that’ll give you points for all your Wendy’s purchases. You’ll earn 10 points for every $1 spent, and once you get 150 points (or $15 spent), you can get a free Jr. Frosty. Plus, you’ll get a free Jr. Frosty on your birthday.
These are just a few of the best Wendy’s menu deals you should use on your next Wendy’s order.
