LEXINGTON, Ky. (WKYT) - If you're selling anything online these days, beware of scam artists looking to rip you off.

Millie Muentes is a stay-at-home mom and an independent sales person with a beauty company. A potential customer contacted her by e-mail. They were interested in buying a large amount of products.

"The person said they worked for a large company and that they were planning a wedding," Muentes says.

The person wanted $1,000 worth of beauty products. They e-mailed Muentes credit card information with a name and billing address. Muentes became suspicious and contacted U.S. Postal Inspectors.

"It was a freight warehouse and that freight warehouse had a foreign address where these items were going to be mailed to," says U.S. Postal Inspector Blanca Alvarez.

The credit card had been stolen. In other words, this was a scam.

"I was really disappointed," Muentes says.

Alvarez says there's an important take away from this story.

"Don't trust anyone you've met online."

Experts also recommend you research before doing business with a person or company you've never met before. If Muentes had fallen for this, she could have lost hundreds of dollars.
