We may be too old to go trick-or-treating, but don't let your age stop you from taking advantage of free or cheap food today, according to the Krazy Coupon Lady.

Here are some places you can go "trick-or-treating" in costume (or in some cases, you don't need one.):

Chipotle Restaurant: Get a $4 burrito if you're wearing a costume.

7-Eleven: The convenience store is offering a buy one, get one free pizza tonight, when you use the app.

Baskin-Robbins: $1.50 scoops. No costume required.

Krispy Kreme: Wear a costume and get a free donut.

Dunkin': DD Perks members can get a medium hot or iced coffee for just $1. This deal is mostly to celebrate the Boston Red Sox winning the World Series. However, Dunkin' also has a costume contest with cash prizes on Instagram.

These two deals are for kids. Sorry grown-ups! Families can save a few bucks, though.

IHOP: Kids 12 and under get a free "Scary Face Pancake." No costume needed.

Applebee’s: Kids can eat free if they wear a costume.
