If for example, a catalogue mistakenly advertised a product for $100 instead of $1000, and a potential customer goes to the store to purchase the product and is informed by a sales assistant that there was a mistake in the printing and informs the customer of the correct price, which then makes the customer be sold for the advertised price or legal action will be taken against the company, does the company have to sell the product to the customer at the price advertised? And what relevant area of contract law will that fall under?
