Under the Single Code of Trade (UCC) per. 2-207 (1), a clear expression of acceptance or written confirmation of an informal agreement may constitute valid acceptance, even if it contains conditions that correspond to or depart from the offer or informal agreement. Additional or derogatory conditions are considered to be proposals to complete the contract in accordance with the UCC, p. 2 to 207 (2). Between traders, such conditions become an integral part of the contract, unless acceptance is the essential requirement that the parties have, subjectively, conduct that demonstrates their consent. After this session of the theory of the spirit of the treaty, a party was able to resist a claim of violation by demonstrating that it did not intend to be bound by the agreement, only if it seemed subjective that it intended to do so. This is not satisfactory because one party does not have the opportunity to know the undisclosed intentions of another party. One party can only act on the basis of what the other party objectively reveals (Lucy V Zehmer, 196 Va 493 84 S.E. 2d 516) to be its intention.
Therefore, a real meeting of minds is not necessary. In fact, it has been argued that the idea of “meeting minds” is a very modern mistake: the judges of the 19th century spoke of the “ad idem consensus” that modern teachers wrongly translated into “meeting spirits”, but which in fact means “agreement with the same cause”.  An invitation to treatment is not an offer, but an indication of a person`s willingness to negotiate a contract. It`s a pre-offer communication. In the UK, Harvey v. Facey is an indication to the owner of the property that he or she might, for example, be interested in a sale at a specified price, was considered an invitation to treatment. Similarly, in the English case Gibson v. Manchester City Council, the words “may be ready to sell” were considered a price notice and therefore not a separate offer, although in another case involving the same policy change (Manchester City Council experienced a political change and stopped the sale of council houses to their tenants) Storer v. Manchester City Council “ the Tribunal found that an agreement had been the signing and restitution of the sale contract by the tenant, because the language of the agreement was sufficiently explicit and the signing on behalf of the Council was a mere formality to be fulfilled. Invitation declarations serve only to collect offers from individuals and not to result in an immediate binding obligation. Courts tend to be consistent in determining invitations to process proposed and accepted invitations in joint transactions.
The display of goods for sale, whether in a display case or on the shelves of a self-service store, is generally treated as an invitation to processing and not as an offer.   n.
