Wendy’s is celebrating Halloween with four-day deals to satisfy your cravings.

The Hello WEENdy’s promotion starts on Monday, October 28th and lasts until All Saints Day. Here’s what the burger chain offers:

• Monday October 28th: ​​A “Buy One Get One” offer on all breakfast sandwiches
• Tuesday, October 29th: A small chocolate Frosty for free with every purchase
• Wednesday, October 30th: A small coffee for free with your purchase
• Thursday, October 31: A free four-piece Saucy Nuggs – get the Spicy Ghost Pepper Saucy Nuggs if you dare, or choose from five other, less spicy flavors.

That’s not all: some soft drinks are just $1 at participating restaurants for a limited time, plus Wendy’s is selling Frosty Boo! Books at a bargain price during the Hello WEENdy promotion. Buuuuh! The books include coupons for five free Jr. Frosty treats and a $1.99 kids meal. You can also grab one by purchasing an adorable Boo! Bag meal, the children’s dessert is served in a glow-in-the-dark Bone Chiller Frosty cup.

Even sweeter: 90 cents from each boo! Book sales will go to the Dave Thomas Foundation for Adoption to “help find forever families for children waiting in foster care.”

All Hello WEENdy offers can be accessed via the Wendy’s app on your phone. This is a great way to earn rewards for free food. Currently, Wendy’s is offering bonus points and a free 10-piece Saucy Nuggs to anyone who opens a new account.
