Have you ever purchased a large item (like a TV) and as you are putting your item into your car, someone approaches you to "borrow" your receipt? You hand over the receipt and the person disappears into the store. You think that it's not a big deal, but little do you know that this is the making of a large scam that happens all of the time. This is the exact dupe that is portrayed in NBC's hit crime drama GOOD GIRLS where the suburban moms use return dupes to hide their money laundering. Return dupes are on the rise and the focus of this week's episode.
