What is the United States law that requires an item to be sold at its listed price?

I believe that in the United States, there is a law that requires items to be sold at the price listed, even if it is accidentally listed at an incorrect price. Is there anyone that can corroborate that fact with a name of a law, the text of it, or any such backing? Even if it's information off some website?

By the way, I'm from New Jersey, if that makes a difference.

I think you are referring to the bait and switch law.

It basically means that if they advertise something for a certain price they MUST sell it for that price (but read the fine print about limited quantity and at what store locations)

What do you mean by listed price? If it is an advertised price and its a typo, no, as long as the seller wasn't intentionally misleading. If it is the price marked on a small item, at say a grocery store, most stores will refund the entire price if you prove the listed price is different than the cost the at the register. If it is the Manufacturer's Suggested Retail Price, it depends on which state you are in, and I don't know New Jersey's law. Some states have laws requiring the customer to be informed in the price is above retail.

More information would be helpful.

No such law. That would be interference with a right of contract. Some companies require, as a condition of sale, that a product be sold at a specific price. That's not a law. That's the company determining its sale price and conditions of sale. Apple computers or Bose Sound Systems are examples. Car manufacturers will give a MSRP for new cars but that is not a requirement of sale since a lot of dealers will discount the MSRP. The closest you could come to a law requiring sales at a listed price would be for regulated utilities so that kilowatt usage must be sold to consumers at the regulatory approved price.

List price is often called "MSRP", or Manufacturer's Suggested Retail Price. There's no law mandating that because, as it's name states, it's only a suggestion. Most businesses won't sell an item above list price, because informed consumers know that it's a rip off.

I think what you're referring to is "False Advertising", and while most businesses will honor their advertisements to avoid civil suits, there's no law compelling them to.

There is no such law. There is a recommended retail price that is usually put on a tag. Businesses are free to raise or lower that price as the market allows.

Its called the "fair trade act". You can research it, it doesn't have to do with International trade, I believe it was enacted around 1911.
