New Port Richey, Florida - A 45-year-old New Port Richey woman is accused of using the notoriety of a top cosmetic brand to make more than a million dollars by selling fake MAC brand cosmetics online.

A federal judge sentenced Tina Oleszczuk to 18 months in federal prison and she has to pay MAC $961,744.75

According to court documents, from March 2012 to March 2014, Oleszczuk, through her company, Cozmetic Delights LLC, sold more than $1 million worth of counterfeit Make-up Art Cosmetics, Inc. ("MAC") cosmetics out of her New Port Richey home.

Investigators say she purchased and had bulk quantities of counterfeit MAC cosmetics delivered from a source in China and then she sold the counterfeit cosmetics as legitimate goods at significantly higher prices. They say Oleszczuk sold them to purchasers across the country through the website for Cozmetic Delights, via E-Bay, and directly to certain wholesale customers.

"Counterfeiting undermines the U.S. economy, robs Americans of jobs, stifles American innovation, and promotes other types of crime," said Susan L. McCormick, special agent in charge of HSI Tampa. "The only ones who benefit from schemes like this are the counterfeiters themselves, and they are benefiting at America's expense."
