MILWAUKEE (WITI) — Who doesn’t want to make a little extra money on the side? You’ve seen the ads for those work-from-home jobs — but Contact 6 says it’s not worth your time.

Counterfeit money orders are at the heart of a scam that starts with victims responding to a job ad that says: “Receive money orders like these in the mail — then go shopping.”

“They would go to Walmart, make purchases, rate their service they received at Walmart, then they would go back to Western Union and mail back the remaining money,” U.S. Postal Inspector David Nitz said.

After following those instructions, the victims would get a surprise. The money orders they deposited into their bank accounts were counterfeit — and they would be in a situation where they had to repay the bank.

Postal inspectors were tipped off to one recent case after customs intercepted a package containing $400,000 worth of counterfeit money orders.

In this specific scheme, there were 750 victims and more than $300,000 in losses.
