If the buyer chooses to accept defective goods, the seller remains responsible for the breach of the warranty.  The harm caused by such a breach of the warranty is the difference in the value of the assumed product and the value of the product that should have been delivered as collateral.  The buyer is always entitled to ancillary and consecutive damages.  It is also always better to get a signed agreement than to depend on the battle of forms to define your terms. A signed agreement will eliminate a lot of uncertainty and make it much more difficult for the other party to add or change conditions.  As an additional exception to the Fraud Act, the Unified Code of Commerce has added a new function that should put the wheels of trade as it is. After verbal agreement, a buyer or seller can prepare and send a “confirmation” of the contract.  If the confirmation is sent between merchants, the party receiving the confirmation may be linked to it, unless it sends a written notice of objection within 10 days of receipt.  This means that the buyer and seller must read their mail and send return letters (or at least handwritten objections) if they feel that the postal agreements received are not accurate.
There are other places in the UCC where merchants can lose contractual rights if they do not read and respond to emails from other merchants.  Q. A merchant gives a credit to a consumer, but he can`t find anything he wants. Does the merchant then have to offer a refund and how long should the credit last? Can a merchant offer a credit instead of a refund? A. First, when a consumer returns goods that do not comply with the contract, the professional cannot require the consumer to accept a credit. The consumer can request a refund by the initial payment method or in the form of a cash payment (or against a position). Similarly, if the merchant has a goodwill return policy that promises a refund, if the consumer changes his mind, the consumer can expect the merchant to keep that promise. If a consumer has been deceived or pressured to accept a credit if he is not obliged to do so, he can always require the merchant to replace it with cash or the initial payment method. On the other hand, if the consumer is not entitled to a refund or makes an informed decision not to exercise that right, the entrepreneur can offer a credit. The professional can determine an expiration date if he informs the consumer of this period at the time of the issue. A buyer may argue that an exclusive or restricted remedy “does not achieve its essential objective.”  If successful, the buyer would have remedies, “as provided for in the single trade code.” However, it is difficult to argue that limited remedies do not meet their essential objective. Failure to do so generally refers to the circumstances a result of the implementation of the agreement and the application of the agreement to new circumstances that the parties do not consider.
 Normally, there is nothing new about buying materials or the possibility that some of these materials may be defective. This is generally and precisely the risk that is envisaged in credit contracts or offers, excluding guarantee and limitation of liability. As a general rule, in commercial cases, the exclusion of the “essential purpose” is only achieved when a seller has refused to make repairs or cannot repair the product.  A response or confirmation may be subject to an agreement on additional or other terms. A buyer could respond to an offer saying, “I will only agree if you agree to lift your liability restrictions and extend your payment terms to 90 days.” That would not be an acceptance.  This is a counter-offer and there is no contract unless the additional or derogatory conditions are accepted.  I was tried 3, 4 times creating the command with 22 individual posts, but it was the same mistake.
