If you plan to shop for your Halloween gear online, time is running out, and the Better Business Bureau wants you to be smart with your money. The National Retail Federation expects people will spend about $12.2 billion on Halloween this year.

If you see a costume or decoration you want to buy, the agency advises you to use caution, especially since some of these entities may only be open for business during the Halloween season. BBB investigator Don O'Brien says the 12-foot-tall skeleton is a popular item this year.

The BBB yearly receives complaints about masquerade costume businesses, which include Halloween stores and websites. Many complaints involve orders that never arrive or are missing items.
