According to the Uniform Commercial Code (UCC) § 2-207 (1), a declaration of final acceptance or written confirmation of an informal agreement may constitute a valid acceptance, even if it contains conditions that supplement or derogate from the offer or informal agreement. Additional or derogating conditions shall be treated as proposals to supplement the contract in accordance with paragraphs 2 to 207 of this section. Between traders, such conditions form part of the contract, except: · The second is retraction. Revocation is present when the bidder states its intention not to enter into the proposed contract.  The Bidder retains control of the Bid at all times prior to acceptance. This implies the right to modify or terminate the offer. 1.It must be an absolute and full acceptance of all the conditions of the offer: § 7, paragraph 1. If there is a derogation, even to a minor extent, between the conditions of acceptance, there is no treaty. In some cases, the assumption may be implicit in a party`s conduct. Suppose a consumer orders a PC with precise specifications for its central processing unit (CPU), hard drive, and memory. After receipt, the consumer finds that the PC does not comply with the specifications. If, in spite of everything, the consumer pays the full amount of the invoice annexed to the CP without dispute, the consumer has effectively notified a legally binding acceptance of the non-conforming thing.
It is not possible to impose silence as a means of acceptance. As a general rule, price offers or price lists alone are not sufficient to constitute offers.  On the contrary, a legally enforceable contract is concluded only when a contract is awarded “in accordance with the proposed terms”.  Therefore, the order is considered an offer. In most cases, the transaction is only completed when the order is accepted.  For example, if you see a price on an e-commerce site, this list is not yet an offer. If you order the product, make an offer that the reseller can accept or decline (for example. B if the product is not in stock or if the price has increased). If the dealer confirms your order, this is an acceptance and the creation of a binding agreement. The restatement states that an offer requires a “manifestation of willingness to make a deal.” Therefore, an offer requires an act that gives another person the power to establish a contractual relationship between the parties. An offer is made if the other person has the right to believe that “his will is invited to this matter and will conclude it”.
Indeed, it has been argued that the idea of “meeting minds” is a totally modern error: nineteenth-century judges spoke of “consensus ad idem,” which modern teachers have mistakenly translated as “meeting the mind,” but actually means “consent to the [same] thing.”  Another type of reserve receipt is available when a recipient promises to pay for a project on condition, for example. B a consignment of goods which reaches its destination on the date indicated in the contract. . . .
