What happens when a merchant displays an item in his store window with a price tag on it? Must the merchant sell the item if the money is offered? It is a fact of law that a display of goods in a store window is not an offer to sell those goods, which can be accepted by a customer saying he will buy them. Instead, the display is known as an invitation by the merchant to receive offers from potential customers. The customer makes the offer to buy and the merchant may accept that offer. Then the goods are sold. But the merchant need not accept the offer, and without such acceptance, the customer cannot obtain the goods or sue the merchant for not letting him have them.
    Unless the seller accepts the offer by taking cash from the customer, the seller is allowed to change his mind. The merchant may want to take back the goods because they have been displayed by mistake or had the wrong price written on them, and he or she would have the legal right to do this.
