Acceptance is the final consent of both parties to the approval of the terms of the offer. While it is customary for the terms of the offer to be negotiated prior to acceptance, if it can be shown that the parties do intend to accept the final terms of the contract through conduct and communications, formal acceptance of an offer is not necessary for it to be legally binding. TERMINATION OF OFFERS recession, declaration of offer cancelled or withdrawn. Supply and acceptance analysis is a traditional approach to contract law. The formula of offer and acceptance, developed in the 19th century, identifies a moment of education when the parties agree. This classic approach to contract formation has been modified by developments in the Estoppel Act, misleading behaviour, misrepresentation, unfair enrichment and the power of acceptance.  Id. See also Extreme Mach. Fabricating, Inc., 49 N.E.3d to 330 (“A] offer of price” may be considered an offer for the formation of a binding contract if there are sufficient details and if it results from the terms of the offer that all that is necessary to mature the offer into a contract is the agreement of the beneficiary.

· The second is revocation. The revocation occurs when the supplier announces its intention not to enter into the proposed agreement.  The supplier retains control of the offer at all times prior to acceptance. This includes the right to modify or terminate the offer. o Unilateral offers – from anyone who performs the deed accept the contract. In order to revoke the revocation, the supplier must take appropriate steps to inform those who may accept – Shuey/USA (convincing precedent) o Bryne/Van Tienhoven – the October 1 offer had not been withdrawn at the time of its acceptance and the contract was therefore concluded with adoption on 11 October, despite the lack of agreement between the parties. The bidder sent a revocation on October 8, but Offeree did not receive it until Oct. 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 are part of the contract, unless the first is the refusal that terminates the power of acceptance.
An example of indirect rejection is a counter-offer. Whether a counter-offer is explicit or tacit, it counts as a refusal and terminates the offer.  In trade agreements, it is considered that the parties intend to be legally bound, unless the parties explicitly state otherwise, as in a contractual document. For example, in the Rose- Frank Co/JR Crompton-Bros Ltd case, an agreement between two commercial parties was not reached because the document stipulated an “honour clause”: “This is not a commercial or legal agreement, but only a declaration of intent by the parties.” o if there is a response to the offer that does not seek to change the terms of the offer. it is not a counter-offer, as it does not reject the f-terms of the offer. It is therefore always open to adoption by Offeree 1.
