The U.S. Secret Service said a Home Depot employee bought prop $100 bills on Amazon and swapped them for genuine currency for four years. The agency charged the man with swapping $387,500 of the store’s real cash with fake bills. The prop bills, which cost $8.96 for a pack of 100 individual $100 bills, look “highly realistic” and he wished Amazon and others didn’t sell them, a U.S. Secret Service agent told The New York Times.
