Invitation to treat: An offer to receive an offer. Goods advertised by a shopkeeper are open to offers from customers. If goods are mistakenly marked with the wrong price, the retailer is not bound to accept that price because he has not offered the goods at that price: he has invited members of the public to make him an offer which he is entitled to accept or reject. A retailer who deliberately or consistently misprices goods, however, may be commiting an offence under the Consumer Information Act.
