The Better Business Bureau warns of Halloween-related scams.

According to the B-B-B scam tracker, fraudsters are setting up fake websites, impersonating stores to offer significantly low prices. Oftentimes, those prices are more than 90% off, with the customer receiving no cost and the fraudsters taking all of the money. Don O'Brien is a scam investigator at the Better Business Bureau.

One tip to avoid the online costume scam: research before you buy and avoid "too good to be true" scams. And check Google reviews. O'Brien says that often someone will leave a review encouraging others to avoid the company.
