Cramming is a form of fraud in which small charges are added to a bill by a third party without the subscriber's consent or disclosure. These may be disguised as a tax or some other common fee, and may be several dollars or even just a few cents. The crammer's intent is that the subscriber will overlook and ultimately pay these small charges. According to the U.S. National Association of Attorneys General, cramming was the 4th most common consumer complaint of 2007 in the United States.
