Here are some pretty surprising spending facts about Halloween. Beware, you may feel a pain in your pocketbook.

According to, we don't just trick or treat and eat candy on Halloween. We spend money, and a lot of it. Parents will spend $1.04 billion, yes billion, dollars on kid's costumes.  That's based on the estimate that there will be 41.1 million trick or treaters between 5-14 years old this year in the U.S.

We are also buying a lot of chocolate, too. We are purchasing so much chocolate at Halloween, that not only has it surpassed Valentine's Day as the top chocolate holiday, but the amount of chocolate purchased for Halloween is now double the amount purchased for Valentine's Day.

And according to the National Retail Federation, Halloween spending has increased 54% since 2005. Overall spending this year is estimated to fall just short of $7 billion.

So, Happy Halloween! Don't eat too much candy, and hold on to your purse!
