I am a strong advocate of Honest Couponing.  If we all are honest and follow the rules of the coupons and the merchants who accept them it can only lead to a better experience and greater savings for us all.

Unfortunately there are people out there who do no follow the rules and try to cash in on scams.  If you come across an individual who you suspect do not confront them but if you feel you must do something inform the manager in a respectful and subtle manner.
