For an acceptance to be valid, it must not only be made by the target recipient, but must also be communicated to the bidder by or with its power of attorney. Contract rules often vary from state to state. If you have questions about whether there has been a valid acceptance of an offer or whether there has been a breach of contract, a contract lawyer who is familiar with contract law and contract design and review can help. Offers to the general public, such as advertisements, contests or contests, can still be considered valid contracts despite the fact that there is usually no declaration of acceptance. If the offer is public, the service is sufficient to satisfy acceptance. For example, if a company offers to give a prize to the winner of a basketball tournament, there is a valid contract between the company and the winner of the basketball tournament. Contracts for the sale of goods fall under Article 2-207 of the Unified Commercial Code, which modifies the mirror image rule. According to §2-207 of the Uniform Commercial Code, acceptance does not necessarily have to reflect the initial offer. On the contrary, an acceptance that deviates from the offer is a valid acceptance without the changes, and the changes become proposals for new agreements that the supplier can accept or reject. As noted above, a contract arises from the acceptance of an offer. Paragraph 2(b) states that “a proposal, if adopted, becomes a promise" and defines “acceptance" as follows: “If the person to whom the proposal is submitted indicates his or her consent, the proposal shall be deemed to have been accepted." Thus, “acceptance" is the manifestation of its acceptance of the terms of the offer by the offer. A contract is concluded only when the supplier receives a declaration of acceptance from the target recipient. Communication can be immediate or at a later date, by e.B. by e-mail or by post. · The first is rejection, which puts an end to the power of acceptance. An example of indirect rejection is a counter-offer. Whether a counter-offer is express or implied, it counts as a rejection and terminates the offer.  If the supplier prescribes some type of acceptance, the acceptance granted accordingly will undoubtedly be a valid acceptance, even if the prescribed type is funny. Thus, if a supplier prescribes the lighting of a match as a method of acceptance and the target recipient lights the match accordingly, the acceptance is effective and complete.
Advertisements are generally not considered offers and are generally treated as a solicitation of an offer. Therefore, no contract is concluded until acceptance by the seller. In one case in New York, for example, Pepsico ran a commercial advertisement suggesting that customers could redeem Pepsi rewards for various prizes, including one for a military fighter jet.  When a person attempted to surrender the required number of points for the aircraft, the court found that no contract had been entered into. The court noted that announcements are not offers unless the terms are clear enough to leave nothing open for further negotiations. If one party leads another party to believe that a contract exists when a contract does not actually exist, there is still no acceptance. Instead, another legal doctrine, the estoppel à ordre, will control the case. One person received an offer by letter.
In response, he wrote a thank you letter, put the letter in his drawer and forgot everything about it. This undeclared acceptance did not constitute an acceptance and therefore did not enter into the contract (Brogden vs Metropolitan Rly. Co). A Minnesota court treated an ad in a newspaper — for fur coat accessories sold for $1.00 — as an offer. The defendant placed two advertisements in the local newspaper at one-week intervals. In the advertisements, the defendant listed the quantity, type of item and price, and added the term “first come, first served." Since the ad was addressed to the target recipient (first come), it was considered an offer. Thus, its acceptance by a buyer would constitute a contract.  If the acceptance is made by spoken or written words or by mail or telegram, this is called explicit acceptance. If acceptance is given by behavior, this is called tacit or tacit acceptance.
If one of the parties acts under the contract or performs the contract instead of simply saying “yes", performance is considered acceptance as long as the performance represents the intentions of both parties. Suppose A offers to pay $10B if B mows A`s lawn.B mows the lawn instead of saying “yes." The performance of B is implicitly considered as acceptance of the contract, although B has never expressly consented to this. Normally, for a contract to be concluded, the target recipient must make a declaration of positive approval on the bidder`s terms. As a general rule, the supplier cannot formulate its offer in such a way that the non-response of the recipient can be interpreted as an acceptance. .
