The concern associated with the practice of negative option billing has its origins in the nature of a contract of purchase and sale, as recognized in common law. As every first year law student learns, such a contract consists of an offer and an acceptance. The history of consumer protection statutes is a chronicle of legislators attempting to ensure that the offer is conveyed without misrepresentation by the vendor to a purchaser who has an opportunity to make an informed choice to accept or refuse the offer. This is because a contract that is made with a consumer who is unaware of key elements of the contract such as price, quantity and quality of the goods to be delivered is subversive of the efficiency of the market as a whole.
