Most state statutes provide that fixing the price of a product or service in agreement with another individual or business is illegal. The general rule provides that a vendor may not in combination with another vendor agree to set a certain price thereby creating a fixed price within a certain market. A business acting on its own and not in concert with another may use legitimate efforts to obtain the best price they can, including their ability to raise prices to the detriment of the general public. Also, conformity of prices within a given product is not illegal unless such conformity was created by a combination of vendors agreeing on a set price. For example, where competitors agree to sell their goods or services at a specified price, minimum price or maximum price and they receive profits from such an agreement, they are in violation of price fixing. Additionally, setting a price to be charged only within a certain area in order to get rid of competition or to create a monopoly is generally illegal under most state laws. A majority of states have also enacted a "Below-Sales-Cost" law wherein businesses may not sell goods below cost if they do so with anti-competitive intent or effect.
