Happy Halloween!

Are you dressing up for Halloween today? According to the National Retail Federation, 67.4 percent of of us will be buying Halloween costumes this year. That's the highest percentage this survey has recorded in its 11-year history.

Even though many more kids dress up than adults, the amount spent breaks down as $1.4 billion on adult costumes and $1.1 billion on children's costumers. On top of that, Americans will also be spending $350 million on costumes for our pets.

All told, Americans are expected to spend $7.4 billion on Halloween this year, including $2.2 billion on candy alone. That breaks down to a total of $77.52 for the average person, up from $75.03 last year. Boo!
