The defendant, Vincent, wanted to purchase a wristwatch from the plaintiff's store. In response to Vincent's enquiry, a store clerk informed him that the price of a particular Rolex men's wristwatch was $900. Vincent told the clerk that she must mean $9 000. The clerk checked the price with a senior store employee who confirmed that the price was $900. The defendant purchased the watch although he suspected that it was seriously underpriced.
When the clerk subsequently realized that the price was actually $9 000, the store brought an action in court for the return of the watch.
