Coupon Fraud is very real, not to mention, very illegal. Most of all, it is not pleasing to God! Here is a great post about fraud caught on tape on Extreme Couponing on TLC. If you coupon, take the time to educate yourself on the subject so you can spot criminal couponing advice when you see one.
As for the show, I do not have cable, so I did not see this one. However, I did see the pilot, and like some parts of it. Of course I would like to see more "realistic" shopping runs on a reality show.
